[EM-27-11] Chaos Expansion Drills XI Season 25 - Lv 40F Walkthrough

[Feel free to share your own strats here, i will add them into main description for archive purpose]

Notes:

• The current boss kit will impede all active skills on the highest attack doll most of the time, so the main strategy is to lower your highest damage dealer to be the 2nd highest attack and let someone, preferably the one who is workable without using their skills, be the 1st place of highest attack among T-dolls. For example: Qj (1st) & Tololo (2nd), Peritya/Mechty (1st) & Klukai (2nd), and so on. Can be achieved simply by swapping their attachments (if their classes correlate to each other).

• The damage dealt by Ravn is much inferior compared to most other ED bosses (likely due to pre-nerfing), making the stage viable to bring a low-rarity team setup. In an optimized setup, it's killable in just 2 turns or maybe less.

• Any healer with multiple target healing and stability replenish capability is required.

• Since the boss possesses lots of stability points, it's always a good idea to reduce its stab points as low as possible but not outright destroy them in one turn. Reduce it and then destroy it in the next turn. That way you have more leeway to deal real damage to them.

• To survive its Burning Discipline AoE attack, you need someone who could soak up its AoE damage. Either by utilizing Area Defense II on vanguard defensive skills with Allay Support attachment sets or any other damage reduction sources. Overheals from Springfield or Centaureissi's invincibility also work well.

• It's generally not a good idea to take its stun attack just to not allow the boss to gain a charge stack, and trying to bait with a summon doesn't work either. So it's recommended to bring someone who could grant Shelter buffs to allies, like Andoris, Sabrina, Groza, etc. This is to mitigate the attack from Charge stacks (3 stab damage per attack x 3 (charge stacks) = 9 stab damage) and prevent them from getting exposed quickly.

this boss is buggy af

anchor is an instant attack for me and doesn't seem to proc on the next turn

the text on the charging frenzy has a mistranslation

as for why the boss is targetting TLL, it's because all the dolls have same hp percentage

this causes the game to trigger a tiebreaker via starting position

this starting position priority is similar to the chaos GS double stacking mechanic

if you switch out TLL with groza in the video, you will see that the boss will start to target groza with his charging attacks instead

if you have trouble keeping up with heals, you can bring cheeta instead

still clears on t11

Well the Anchor Deterrence activate immediately, unlike the Burning Discipline one who proc at next turn.

Yes, I'm aware but forgot to point that out lol, will add to note later

Actually I've tried that, but it's still targeting my Tololo instead of the one who is near it. It seems the logic behind that is poor to the point the patterns aren't recognizable (except they prefer to choose the lowest HP% if available).

I've also tried to bring completely different dolls with Tololo in them, and the charge still aims at her until Yoohee comes and the boss begins to switch to her instead of TLL.

nono it's the starting position

the tile behind tll's starting position has the highest priority on the map try it

if a doll deploys on there, the boss will always tiebreaker that doll

the tile tll is on has the 2nd highest priority and so on

it's kinda map dependant

Tried it with Cheeta but her ultimate CD is kinda messing the cycle, so I switch to Cologne instead

[gilded latch]

this is an example

I use cheeta to gurantee full health when colphne is stuck healing stab etc

[autumn tree]

And Cheeta didn't give enough stability replenish to team than Cologne so..
