Delicious new christmas waifu. Made entirely using natural ingredients.

I'm currently feeling pretty salty about the 13 summons with no drop on her gate. I wanted this one.

Stats/Arena/Animation

• Silvie's stats are nuke focused. High ATK, low DEF. She's a nuker. REC's higher than expected, but ultimately means nothing much.
• She has a threshold angel idol, which is normally a good trait for the colloseum. Do note that Silvie lacks any other valuable traits for the colloseum (no immunities, no normal AoEs, no angel idol bypass), so while usable, she's not Azurai tier as a filler unit.
• Due to her double attack, Silvie's animation is significantly different between BB and SBB. In both cases the main AoE is a pure spark blanket (a single 9 frame gap in the middle of the BB); however, for the BB that spark blanket begins much earlier. When using the SBB, Silvie's single target attack happens at the time the BB's AoE would normally start, followed by the AoE 0.75 seconds later. The single target hits are very spread out, though conform to the same 3f multiple as the main AoE.
  • This causes her to have vastly different requirements for being sparked effectively with either attack. Theoretically, a large enough spark blanket with a good start time can perfect spark both her BB and SBB, but the difference in her first and last hits on SBB means you need very precise placement of the spark blanket's animation. It needs to start on or before her 24th frame and last through to her 141st frame, covering a total duration of 117 frames minimum.
    • 117 frames is the length of a 40 hit spark blanket, to give you an idea of the precision you'd need. In addition, many spark blankets start late enough that you'll also need careful squad position just to make sure the spark blanket reaches the target in time to spark her first hit.
  • Notably, Silvie's movement type and speed allow her to be dupe sparked through the same placements used for Rize, Avant and so on. Also notably, her BB will fully spark the single target part of her SBB's animation, though the difference in AoE placements means neither attack will actually be perfect sparked if mixing her BB and SBB.
  • Meanwhile her UBB is an extension of her BB, just to make things harder to work with. The same spark blanket mentioned earlier could still cover the entire thing, however.

LS

• Silvie's LS grants 50% ATK/HP, 50% ATK/DEF/REC when over 50% BB Gauge, 130% spark damage and 2-3 BC on Spark
  • The stats aren't particularly impressive. Many OE units have 50% all stats baseline, after all. DEF stacking can be useful in an LS, but she's far from the only option for it.
  • Spark damage remains the most powerful damage boost in the game. Many people have seen it as uninteresting for most of the OE cycle, but that doesn't mean it isn't strong.
  • Spark BC is great and every squad needs some. Whether a squad needs extra from an LS after the almost certain buff form is another question, but sometimes the answer is yes.
• The LS has decent utility, but lacks the damage a BB ATK/Spark Damage hybrid would have. You can basically think of this is as a non-mono Eze for the most part.

ES

• Silvie's ES is a simple two-parter: 50% spark damage, angel idol at 20% HP.
  • As a unit primarily suited for nuking, the spark damage helps Silvie nuke harder.
  • The angel idol seems unsuited to her, but it's free, and has interesting uses in raids in particular - if you know a boss can't bypass it, havng an angel idol unit around effectively lets you run away for free as long as you pay attention to whether it's been triggered.
    • Also nice for collo, though I already mentioned she lacks features to bring her to top tier status.

BB

• Silvie's BB is an HP-scaled AoE that mostly functions like a spark blanket. It grants the entire squad 150% ATK/DEF/REC, grants Silvie herself an extra 100% ATK/DEF/REC and also gives 4-7 BC when attacked and a 10% chance angel idol.
  • As it's only BB tier, the HP scaling isn't necessarily going to bring the BB to the ATK cap, though it can come close with most generic setups. Assuming just 400% BB ATK as a buff and 150% HP total from LS, SP, spheres and elgifs, Silvie will only be 350% ATK short of the damage cap when using her BB. Getting more than that in the current state of the game is actually relatively trivial.
  • Tri-stat is nice. Tri-stat that can have every stat enhanced to 180% via SP option is very nice. The most important part of this is generally the DEF%, but the other stats can also be converted into DEF and/or act as damage boosts.
  • Self tri-stat is just a nice boost for Silvie that basically offsets her low DEF. The other stats arguably end up being irrelevant asides from converting them into even more DEF due to her HP scaling, though her ST portion of her SBB still gets decent benefit from ATK.
    • She actually gets an enhancement to brings the value here up to 130%, but it doesn't seem worth using. You don't really need to turn Silvie into a tank and the rest of her enhancements generally boost damage more.
  • BC when attacked is a squad standard buff. The majority of squads in end-game content should have a source of this, so having it on her BB furthers Silvie's viability as a unit.
  • The final buff noted on her BB is a chance-based angel idol. This effect places a buff on your units that has a 10% chance to save their life when they hit 0 HP.
    • An important factor of this buff is that the revival chance is determined when your units die. Repeatedly applying the buff does not increase survival chances, and the buff icon will display after just one usage.
  • There's an SP enhancement to allow Silvie's BB effects to last an extra turn. This enhancement mainly exists to let her use her SBB more often, theretically 3 times per 4 turns instead of 2 time per 3 turns.

SBB

• Silvie's SBB is a dual attack; an HP-scaled AoE that functions as a 25 hit spark blanket with a late startup time, and a low hit count ST attack with no special features. It grants the squad spark damage and spark BC when used, as well as giving Silvie an additional spark damage self-buff.
  • The HP-scaled AoE here will have no difficulty reaching the damage cap in any general OE LS pairing that's commonly used. Adding further ATK or HP is generally only going to inrease the buffer zone for the amount of damage Silvie can take in raids before her damage output starts to decrease.
  • The extra ST attack here will deal significant damage to your main target, assuming you can spark it well. If you're maintaining Silvie's BB and a BB ATK buff, it should be dealing around 50-60% of the damage her AoE deals (and also generally more than any non-nuke units in your squad). However, as I noted before making spark setups that cover Silvie's SBB entirely is tricky, though definitely worth doing.
    • If you're not aware by this point in the game, BB skills which consist of multiple attacks calculate each separate attack individually with their own RNG and buffs/base stats being recalculated for each attack, allowing them to effectively bypass the ATK cap (99999 before Crit/EWD/Spark/Hit Count multipliers) against whatever targets are hit by multiple attacks.
  • Spark damage is good damage. Silvie can hit 150% buff with an SP enhancement, which is the current top tier for the BB/SBB tier buff form.
  • Self-spark damage buffs are additive to general spark buffs; assuming you give Silvie the enhancement to her regular buff, she gives herself 200% spark damage when using her SBB.
  • Spark BC is good BC. It's another standard buff that most squads want to carry at this point in time, and yet another reason to say Silvie has great utility.

UBB

• Yet another HP-scaled AoE (that damage caps without any HP increases or buffs). Silvie's UBB grants the squad 300% ATK/DEF/REC, 300% spark damage and a Holia-type angel idol with the same 80% proc chance. In addition to all of that, Silvie gives herself an extra 100% spark damage.
  • Ironically due to the lack of a double attack this UBB will deal less damage than Silvie's SBB against a single target if she has enough spark damage from LS and spheres. That said, the buffs more than make up for that over the rest of your squad and Silvie's following turns.
  • We've gone over tri-stat already. Obviously 300% is a huge buff to DEF, while the ATK is high enough to be considered significant for most non-Silvie units. That said, this alone doesn't replace a mitigation UBB.
  • The spark damage is just more raw damage. At the current point in time spark damage is the least likely to be resisted of the 3 major damage multipliers (spark, crit, EWD), and there is content where it's the only one of them that works at all. In that kind of content, a UBB that focuses purely on ATK and spark damage is probably the best kind of damage UBB.
  • Silvie also gives herself more spark damage. Between her UBB, SBB, ES and SP enhancements she can have 780% spark damage before considering LS, spheres and elgifs. Pretty huge.
  • Finally there's the chance-based angel idol again. This effect, when on a UBB, is known to be unremovable except by unit death (which will either trigger it and remove it, or let the unit die which also removes it), which led to Holia being very valuable in some trials. Silvie having it with a massive damage UBB is just going to make those kinds of trials even easier, to be honest.

Damage Comparisons

She's a nuker, so I'll cover this quickly.

Against other popular dual attack nukers, there are situations where Silvie is the best choice, and situations where she is not the best choice for damage specifically. She has much better utility than just about every other nuker and should be the go to choice for raids and endgame content as a result.

As for when she wins: Silvie has higher personal spark damage than all other dual attack nukers, reaching 250% personal spark damage. Lasswell comes closest after that at 220%. In addition she has slightly higher base ATK than Lasswell, making it difficult for him to make up that difference through his slightly higher ATK% on his single target atack. So if we take crit out of the equation, Silvie can have higher damage than the previous best nuke in the game. As there is plenty of content where this is the case, she can act as the superior nuker in mostly raid and trial content.

That said, this is dependent on focusing on her SBB, and she will fall behind in damage if you're juggling her BB and SBB for the utility buffs.

In crittable content, as she has no crit damage and Lasswell and Rize both do, she loses to them with no real way to bring it back unless you manage to crit cap her through pingu spheres.

SP Enhancements

Nuke unit, damage enhancements. /section

• 20 SP: 20% All Stats
  • Standard filler.
  • HP will generally increase the damage of her BB a lot unless you cap it already, while ATK will increase the damage of her SBB's single target attack very slightly.
    • Bonus to BB damage is 100% AoE damage, bonus to SBB is 20% ST damage.
  • As mentioned earlier, and relevatn to the next two enhancements as well, her SBB generally doesn't need any additional HP to damage cap, but it does provide a buffer against raid damage to maintain her damage output.
• 10 SP: 20%-> 30% All Stats
  • An enhancement to the prior option. Requires you to have the 20% all stats first.
    • Bonus to BB damage is 150% AoE damage, SBB gets 30% ST damage.
  • More filler.
• 20 SP: 30% HP
  • Filler. More HP.
  • Depending on whether you're focusing on SBB use or BB use, you'll get more use out of either this or 20% all stats. It's also dependent on the number of targets.
• 10 SP: 70% Spark Damage
  • Nuke build filler.
  • Always good, unlike the previous options which are highly dependent on whether you already cap her damage.
• 10 SP: 70%->100 Spark Damage
  • More spark damage for the spark goddess.
  • Less cost-effective, but I expect most builds can afford it anyways.
• 30 SP: Enhances BB's boost to Atk, Def, Rec ( 30%) effect
  • Makes her BB's stat boost a top-tier 180% ATK/DEF/REC buff.
  • It's enough to be signficant for squad survival rates, and can generally fit into builds by giving up on the all stats passive which is likely to only increase Silvie's damage by the same amount.
• 30 SP: Enhances BB's boost to own Atk, Def, Rec ( 30%) effect
  • The same as above, but only for Silvie.
  • It costs the same as getting 30% all stats. You don't really have enough points to spare to get both, so if you want 30% all stats, get 30% all stats?
• 30 SP: Allows BB effects to last 1 more turn
  • Lets you get one more SBB every 4 turns.
  • Angel idol has effectively infinite duration, so you don't need this for that.
  • This sounds like a lot of damage, but it's actually not very significant. You get 66% uptime on the ST attack instead of 75% uptime - over 12 attacks you'll get 9 SBB/3 BB instead of 8 SBB/4 BB, and especially if your BB is damage capped that's effectively just one extra ST attack per 12 turns. You do get access to more of the damage sooner, but overall it's not a massive buff.
  • In a long encounter it may be a better damage boost than taking her All Stats option for the same price, as that only increases her ST damage by about 2-3% at best (and the ST isn't likely to even be 50% of her total damage) and you may already be capped on the BB damage. It's more dependent on the latter point.
• 30 SP: Enhances SBB's BB gauge boost on Spark ( 1-1 BC) effect
  • More spark BC.
  • For what it's worth, if you're using a squad that sparks well you likely don't need any additional spark BC beyond her 2-3 baseline. It may have some relevance against BB Fill Rate debuffs.
• 30 SP: Enhances SBB/UBB's Spark damage ( 30%) boost effect
  • Standard spark damage buff buff.
  • It's great for squad damage overall and she doesn't really have enough utility options to make it unaffordable. Good choice.
• 30 SP: Allows UBB effects to last 1 more turn
  • One extra turn of high damage. Good if you need one last turn of nuking, I suppose.
  • Angel idol buff has no duration again, so unaffected by this.

SP Builds

Not much to discuss here. We're really just choosing between optimal damage or less damage plus some utility. My personal choice would be the utility build as shown below, as I want her to be more useful as a raid sub and feel it's worth the damage loss to have 180% tri-stat instead of 150% tri-stat.

* Utility build can take additional spark BC in these slots if you want it, but I doubt it's necessary

The choice between 30% HP and 20% All Stats is dependent on how much damage/HP you're getting through your LS, sphere and Elgif slots. If you're getting enough to cover at least 350% BB modifier (10% HP is worth 40% for the BB) then adding more HP through SP is only giving her a buffer after taking damage. In such a case, the all-stats makes more sense as it's still a damage increase for her SBB's single target damage.

If you're not getting enough ATK through HP/buffs to cap SBB damage and can make the most of the 30% HP option, it's likely to be more valuable than the 20% all stats. Against two targets they work out about equal for total damage, and against 3 targets or more 30% HP adds more to total damage (4 targets with 1 BB duration).

Overall the difference is quite small and you can just choose based on whether you'd prefer more HP or more DEF.

Oh, and I guess you can do a max defensive build with 30% all stats, 30% HP, 30% stat buff and 100% spark damage (because the self buff is too expensive at that point), but Silvie's not really a tank unit so I don't think it's suitable.

My final conclusion on Silvie is that she's a very strong unit. Considering she's a very high-end nuker, the sheer amount of utility between her BB and SBB and the high damage of her BB making it less punishing to switch between them means she unusually has a place in endgame content squads where other nukers would be left out due to not bringing important buffs.

We can either see this girl as a nuker, or we can see her as a Tri-stat BC on hit Spark Damage Spark BC buffer with an added angel idol on BB and UBB as additional gravy, who happens to hit the damage cap, have a double attack and have extreme spark damage passives.

So yeah. I'm not happy with my lack of pulling her. Praying for the remaining login campaign gems to get me something nice over here.
