How to beat Ceremonial Beast
- Chip the beast’s HP to just above 150, then burst it down as far as possible in a single turn. This way, when you’re hit with Ringing (1 card per turn), the beast is already low enough to finish off. Don’t trigger the stun early with chip damage — plan the burst.
- Bring the boss close to 150 HP without going under, then burst past it
- Save your biggest damage for the turn after the stun
- The Ringing turn is dangerous — make sure you have enough HP to survive one card’s worth of Block
