The gimmick

What Ceremonial Beast does

The one thing that defines this fight — read this before you draft your route.

A dormant brute that spends its opening turns powering up — stacking Strength and a Ritual-style per-turn buff — before waking into escalating multi-hit attacks. The longer the fight runs, the harder every hit lands, so it is fundamentally a race against its own scaling.

Game plan

How to beat Ceremonial Beast

Ordered priorities for the fight. Tools shift by deck, but these beats hold across most archetypes.

  1. Use the early dormant turns to set up: play your Powers, draw through your deck, and bank block instead of pinging it awake before you are ready.
  2. Once it wakes, prioritise Weak every turn — because its threat comes from multi-hit attacks, reducing per-hit damage with Weak is far better than raw block.
  3. Apply Vulnerable to compress the fight; its HP pool is the largest single target in Act 1, so you want to be killing it, not trading turns with a stacking buff.
  4. Have a real burst turn planned for when it has ramped — smoothing block across low rolls loses the long game here.

Class-specific tips

How each kit leans into this matchup. Open a class hub for full builds and card priorities.

Ironclad builds →

Ironclad loves this one: front-loaded Strength plus a Vulnerable enabler lets you out-race the ramp before its multi-hits spike.

Silent builds →

Silent can lean on Weak application and poison — poison ticks ignore the block-vs-burst tension entirely while you stall the wake-up.
