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%.
