FGO NA – Illya’s Castle 2025 – Berser-CAR Boss Fight 3T (double Bazett)

The necessary steps to 3T this battle are:
Double Bazett NP on turn 2, with one Bazett capable of breaking Berser-CAR with a single counter (event damage CE or Black Grail); the double Bazett NP must be done on turn 2 to deplete all Berser-CAR’s Guts (doesn’t work if done on turn 3).
AoE NP on turn 2 capable of breaking Berser-CAR (event damage CE or Black Grail); we must clear all the mobs to give Berser-CAR both actions that turn to activate Bazett’s counter.
Either burn or poison or curse must be inflicted on turn 2; we can’t wait until turn 3 if we want to deplete all Berser-CAR’s Guts and we can’t inflict it on turn 1 since he clears his debuff on first break.
One AoE NP on turn 3; we must clear all the mobs to give Berser-CAR both actions that turn to activate Bazett’s counter.
One Bazett NP on turn 3; this will leave just one Guts that can be depleted with any facecard.

If Berser-CAR had just one fewer Guts or if he didn’t clear his debuffs on first break, we could 3T this fight without needing to use command spells: for example using Habetrot as AoE DPS that could swap out on the last turn for Ruler Skadi (with Kaleidoscope CE) to clear the last wave and charge Bazett (with Kaleidoscope CE) to full if we saved her own charge skill.

As it stands, I can’t think of any other way to satisfy all the conditions listed above and still have the charge/refund needed on turn 3 without using command spells.


REGARDING SUPER DIFFICULT STAGE QUESTS
They are not really challenge quests and since we are forced to use a party of 5 supports, we can’t min-turn nor solo them, that’s why I didn’t bother to record my clears. Here is the list of the servants I’ve used to clear each stage:
Stage 1: Summer BB can lock Illya’s cards to reduce the Nobu’s Guts duration faster.
Stage 2: Bazett can speed up the clear by a few turns, since she can kill the golems on the same turn their break bar is broken
Stage 3: Setanta has an easier time dealing with Jaguar Man given his powermod against wild beast enemies
Stage 4: Van Gogh can stun all the enemies repeatedly to avoid them passing the bombs to you (immobilizing them is the only way to avoid the bombs that explode at the end of the enemy turn)
Stage 5: Tiamat has raw NP charge (both active and passive) to bypass the enemies’ NP gain debuffs and to keep the party alive, plus she can buff herself with her NP so even the enemies’ buff removal is not that harmful.
Stage 6: Draco has class advantage against all enemies in this battle, so she has an easier time killing any of them to get the necessary buffs for the final boss.
