One with the Shadows

Rin Tohsaka
BOSS
RIN TOHSAKA

One with the Shadows is the 3rd stage of The Hidden Grail War. Previous stage: Sins of the Abyss. Next stage: Beyond Springtide.

STRATEGY

Hardly a challenge: Rin Tohsaka at 100% behind Croco, Those Guys, Sir Seal and Gory.

  • Dragon Cat with solid meatshields and Whale Cat handle it; Butterfly Cat removes the boss quickly once through the peons.
  • Don't spend a Treasure Radar on Li'l Sakura here (25%) — the next stage drops her at 45%.
