The gimmick
What Aeonglass does
The one thing that defines this fight — read this before you draft your route.
The newest Act 3 gatekeeper, added in patch 0.105.0 to replace the removed Doormaker. Its Withering Presence punishes wide, cheap-card decks: after you play enough non-status cards across the fight, it forces a Wither status card on you (a 1-energy Retain/Exhaust card that damages you if left in hand). It runs a short rotating pattern with a permanent self-buff each cycle, so finishing fast matters.

How to beat Aeonglass
Ordered priorities for the fight. Tools shift by deck, but these beats hold across most archetypes.
- Pick a lane: either 'quality over quantity' — win with a few big or X-cost cards so you rarely trip the Wither counter — or run discard/exhaust to scrub Withers as they appear.
- Because it permanently buffs itself each cycle, treat this as a speed check: closing in as few cycles as possible is the goal.
- Do not ignore Withers in hand at end of turn — clear, play, or cycle them; left sitting, they chip you every turn.
- Front-load mitigation for its short attack rotation, and check live tooltips: its moveset and the Wither rules were retuned in 0.106.0.

Class-specific tips
How each kit leans into this matchup. Open a class hub for full builds and card priorities.
Ironclad's exhaust package and big single hits are an ideal fit — scrub Withers and win on fat swings rather than card volume.
Silent's discard tools cycle Withers away, but mind the counter: a wide knives turn can trip Withering Presence, so balance it.
