I recently cleared the Annihilation difficulty and wanted to share my success and strategy with the community. I have a relatively shallow monster box, so I’m pretty chuffed. (TL;DR at bottom.)
You can see my success here: https://ibb.co/b15wSRw – I’m just lucky I didn’t get a GAME OVER for taking screenshot at the end. You lose if you switch out of the game to another app during this dungeon.
Leader & Friend
Your leader and friend need to have serious tankiness between them; if you have a 2xHP and 1.5xHP combined (or shield equivalent) you can probably tank all the hits. You’re also going to need a resolve killer, and probably a 7×6 board – no card has both of those in one leader skill (yet). While I used Feygoran/Aten, Aten/Dyer is commonly suggested as well. One or both of these cards need the VDP latent. I highly recommend Aten with all the killer awakens, although Dyer can put out some decent damage too.
There are three one-hit pre-emptives in this dungeon:
Floor 5 – 82874
Floot 7 – 72800
Floor 10 – 116442
It can be hard (for me, anyway) to put together a team that has enough HP/shield to cover that last pre-emptive while also having auto FUA in the leader skill and a 7×6 board.
I ended up using Feygoran with a friend’s Aten. This is enough to tank the first two pre-emptives but not the floor 10 pre-emptive. I included an active skill shield from Raphael to pop on floor 9 just before clearing it. If your team can tank the floor 5 pre-emptive, you only need a 32% shield on floor 9. I used the Raphael that I did because he was also a God-type HP statstick for use with Aten.
Hera-Ur will have resolve and do a Jammer/Fire skyfall; you can defeat this with the latent jammer skyfall resist – but I don’t have it.
Instead I used #5625 (Pumpkin Devil) that we could all get by farming Halloween Night recently; I assisted it onto a Revo Vritra who had a 6 turn base cooldown. On the first floor it was still 2 turns to be ready. I didn’t have any other low-CD black God-type cards with big HP to assist it onto.
(I am a fan of eliminating the jammer skyfall and leaving the fire orb skyfall because it increases the odds of skyfall combos.)
Combo to sweep, use leader skill to FUA
Beorc is trouble because of the Damage Void + Resolve + Att Absorb
You can mitigate the light attribute absorb by putting those cards closer to the left of your team; so far as I can tell, damage is dealt from left to right, all the primary attributes first, then all the secondary attributes left to right. If you have a Dyer or Aten helper, your last secondary attribute should be Fire/Red with VDP latent.
If you can combo all Att+ Hearts, do it and sweep. If you cannot, pop the Halloween Pumpkin (if you have it) to refresh the orbs.
You should have Jammer+ resist in case you don’t sweep immediately. She will give you a warning about jammers and try to make some.
Let the leader skill finish off her resolve.
Awoken Skill Bind 7 turns pre-emptive. You probably have one of these cards, but I used Feygoran.
Pop your awoken bind clear, then combo to sweep, use leader skill to FUA
Combo to sweep, use leader skill to FUA. You need 5Att+Heal in order to pierce the damage void.
If you want to bring an active to reset the board, you should have space for it on the team.
Mass attack is ideal here – I used the badge. If you have a max-skilled Bastet and triggered it early, it should be back up.
Zeus has att absorb while Hera has dmg absorb.
If you can’t take the 116442 pre-emptive for floor 10, pop your damage shield.
Do your second-best combo!
That’s it. Good Luck!
82,874 HP or equivalent with 32% or better 1-turn shield
