Info and detailed stats in this thread.

Again, this is an extremely brief overview of how the new units will fit into the game, not a side-by-side in-depth comparison.

Crimson Spear Goddess Claire

• Outclasses every spark buffer in the game, unless for some reason you need the BC fill on spark LS from Rosetta.

• She's like an Elza Felneus (or Uda if that's your thing) rolled into one with 30 Hits 80% SBB Spark buff and 30% BC Droprate.

• Personally I feel like her LS is kind of lacking, because I'd rather take a BC fill on spark or even extra BC gen on spark than 30% ATK/DEF.

Blue Sword God Kurt

• His BB (NOT SBB) places you at the CRIT cap, which futher synergies with his LS (boosts CRIT damage by 150%). The 30% HP will be a godsend for RC 4/5 where surviving is an issue, while still boosting DPS by a lot.

• His SBB has the same 60% CRIT buff as his BB, but his UBB has a 70% CRIT buff which either means that the cap has been removed or that Alim will be implementing more CRIT-resistant bosses in the near future.

• The only issue I can possibly see with him is that you might accidentally do too much damage and lower bosses under critical HP thresholds when you don't want to ^{First World Problems Eh?} .

NOTE: If I'm understanding the patch notes correctly, when these two (Claire Kurt) are used together, their ES will activate and give them a free Malice Jewel. Don't know how this fits into Gacha laws but it means that their stats are tier above almost every other unit in the game.

Brave Emerald God Keido

• LS is the best 5-Lights LS, giving 100% ATK as well as 30% Fill Rate Boost and Reduces BB Cost by 20%.

• He hits all elements super effectively on his SBB and grants 4 elemental buffs. His UBB gives all element buffs. Outclasses Shida in every way unless you need instant BC fill.

• Extremely strong Arena unit, 24 DC, and with both an ATK and BB buffing LS, means that random rules will screw over your team less often. Also hits most units for super effective damage on his BB (although it should wipe most units regardless).

• ES is pseudo-Hadaron, not very useful but its still a bonus. Overall, this unit's uses will probably be for Element-Buffing Arena.

Thunder Phoenix Goddess Diana

• LS is basically a Matah LS HC effectiveness. Synergizes with her HC Droprate Buff.

• Offers Matah's SBB buffs to the whole team on her BB (-BC droprate HC Droprate), and offers stronger versions of her buffs with an 18-hit attack on her SBB. So basically she outclasses Matah COMPLETELY. Even VS Earth bosses I'd probably say that she's a better pick.

• UBB deals with BB drain really well, or even general attacks, gives a 50BC fill on hit which basically means that everyone's SBB will be full. I don't know if it is as useful as some of the other buffs, but still valuable in certain situations.

• ES gives 4 BC fill per turn to herself which definitely helps with BC management, but might be overkill as Leomurg takes care of that pretty well.

Wisdom God Fadal

• Pandemic Spread LS with a better Cardes cashback. Good for bosses that are susceptible to statuses. ES gives BC when hit, which helps with bosses that attack a lot but not something that stands out greatly.

• Inflicts ATK/DEF down on her BB/SBB/UBB, only issue I see is that it only lasts for 1 turn. Also gives chance to inflict Curse/Weaken on BB and Poison/Injury on SBB. TBH I don't really like this as it means you'll have to use BB when otherwise you could be using SBB.

• Gives Torah a good run for her money, his UBB gives 100% proc rate on ATK/DEF down and Statuses, but I don't think he'll be seen outside a few niche situations.

Sacred Star Goddess Ivris

• LS is pretty redundant, it heals and prevents ailments which is what she does.

• Dark's first (2nd if you count Alice) premium healer. Outclasses Rigness/Ulkina/Tree as she also has an 18 hit attack tied to her BB heal. It should be mentioned that she doesn't prevent statuses on her BB though.

• SBB is purely a heal, that also prevents ailiments and has an 8 BC insta-fill for other units. UBB is a 22 hit attack that also cures ailments and gives 2 units an angel idol buff. Has its niche uses for lowering bosses under HP thresholds.

• ES is (I don't know if I'm understanding it perfectly) an angel idol buff to herself, which synergizes with her role of a healer perfectly.
