Here is my Bomb Family strategy. Before you read, make sure to look at /u/Sinzar_'s post on beating this fight. It is a superb guide and, generally, a better strategy than this one. It is thorough and innovative and if you are having trouble with the battle it will surely help you. Reading the comments on his post, I found a lot of people said an evade tank was required and many people didn't have one (his own strategy could still work simply bringing an evade tank friend). I tried to devise a strategy that was budget-friendly (I used Pod 153 but I have some suggestions for alternatives below) but wouldn't use evade just to see if it was possible. Here is my result:

Veritas of the Earth CeriusExdeathTimothyLulu (I'm sorry this used to show their icons, if someone knows how to fix that kindly let me know in the comments).

Following Sinzar's lead, I did this with 5 units so that you can add a sixth to help with whatever is giving you the most trouble: re-raise for VoE, a better break than Tim (Bran is a strict upgrade for this strategy, and Lid and VoL are huge upgrades), a healer or a second damage dealer to make the 60% nukes easier to manage, a summoner to make sure you can get the Esper mission, or a whole other unit who can provide some mitigation if you don't have Pod 153, Cowered Courage, or Heaven's Guidance.

Plan

The idea was to find a way to absorb the physical damage with a typical physical tank using as much support as necessary, and then finding a damage dealer that could work within those constraints. Enter Lulu, the only one I could think of who can get a high mod on both an Ice and a Fire skill (the new character Mediena would probably be better but I don't have her) and also wipe the Thunder bomb juniors without breaking stride. It turns out with a good break and some buffs, Lulu's 12x from double Firaja or double Blizzaja is capable of dealing enough damage to either big bomb to kill them from above 60%. Particularly:

As you can see, if you bring MS Nichol to the fight you significantly reduce the damage requirements (even a 50% break will be doable to kill the boss from 60%) and if you bring Lid of VotL to the fight then you don't even need to buff Lulu at all. In fact, if you bring Lid or VoL and Nichol, you can even kill the boss from 100% and not risk any threshold nonsense whatsoever.

The particular approach I took (Tim break with Faith buff) Lulu will average 53.7% of the boss's health, this is why in the video Exdeath has to "partner" her spells with the equivalent -ga spell to give her the 1-chain elemental boost of 0.3.

Setup

So there are a number of roles that need to be filled in order to make this strategy work:

• Someone has to AoE Cover
• Someone has to heal that tank to full or mostly full each turn
• Someone has to dispel the Mom Bomb every turn
• The party requires 100% uptime on 100% Fire & Ice Resist
• Someone has to provoke the imperils (not the cover tank as he has to have someone to cover)
• Someone has to do enough damage to kill the boss from 60 %
• To accomplish the above, someone has to break
• Someone has to use physical or general (better to find a way to get both) mitigation 100% uptime
• Someone needs a damaging LB
• Someone has to hide at the end (depends)

I'll summarize these roles in the table:

Turn by Turn

Here is every action taken for reference.

Substitutions

Pod 153: If you don't have access to Pod 153, you can use Barusa's TMR or Orran's TMR instead, or you can bring Vayne or Divine Soleil. You might be able to use a re-raiser for VoE himself as well.

Lulu: You probably need a friend Lulu or you'll need to bring two damage dealers so that you can cover both fire and ice elements and do one very large hit (with the break). Mediena would work too.

Defensive TMR: You have some room with your VoE if you don't have the Patriotic Recalls or the Ziedrich, but it is finite--he will have to absorb some big hits. The nice thing is the first turn is or is very close to the most damage he will take all battle, so you'll know right away if he's tough enough. If you can bring a general mitigation (Crowe, 9S, MS Nichol, Orran TMR etc.,) and a physical mitigation (Pod, Barusa TMR, Vayne) it will greatly help him survive that first turn. My VoE has good gear, but I'm 240/390 on HP pots for him and the closest he came to dying was 3396/12881 (26.3% hp remaining).

Improvements

Bran with Odin for Timothy is just a straight upgrade--his better Break on the LB makes a big difference and if you enhance him he can provide 15% general mitigation if you have a free turn.
