Raid TL;DR

• In this raid, shields are crucial. Healing is reduced to 10% effectiveness, but shielded students will take half damage. Damage is unavoidable and significant.
• Goz has 100 DEF. DEF Down is worthless here.
• On TOR and below, Goz's groggy gauge is 80% hp. On LUN, it's 2B, so it's only achievable via a new mechanic introduced in P2.
• Goz has 2 Phases, a train phase and a stage phase.
• Train Phase
  • At the start, there will be 4 bear mobs and 4 rabbit mobs on the field. They can significantly hurt your team if left alive. If invested enough, your team may be able to deal with them solely with AA.
  • Goz will target the closest student, periodically throwing a walking bomb that does significant damage.
  • Goz will also summon trains on one side, the other side, and both sides. Those in the inner area will take significant damage, while those in the outer area will take half damage. Bring a reposition to avoid getting hit.
  • After the trains pass, 2 bear mobs and 2 rabbit mobs per train will spawn.
  • This phase lasts until 18M/30M/150M HP for INS/TOR/LUN.
• Stage Phase
  • Goz will split into 3, with one being the real Goz that can take damage, identified by card colors on spawn. Blue cards indicate the real Goz, while red cards indicate the copies. Real Goz positions are no longer RNG-based.
  • After the split, Goz will immediately throw walking bombs at the 3 closest students. If you have a squishy student, make sure she's the furthest away.
  • Goz will next do a hat shuffle. On TOR and below, the coin hat will ALWAYS be in front of the real Goz. On LUN, it's not always the case.
    • On LUN only, being in the coin hat's hitbox will grant a cost recovery buff for the yellow coin or a damage buff for the blue coin.
  • Goz will then create three circles on the floor. Standing in the real Goz's circle will protect you from damage EVEN IF IT IS OVERLAPPING THE OTHER ONES. Afterwards, the fakes will die, and Goz will split once again. (Not entirely sure, but after 3 cycles, Goz seems to spam only this attack, at least on LUN runs. TOR and below runs usually finish before this point, or get disrupted by groggy.)
    • On LUN only, the groggy meter will fill by 1/8 and your students in the real circle will get a cost recovery buff.
