Patch 37.0.2 launches today, bringing balance changes to Standard, Wild, Arena, and Battlegrounds. The update reduces the strength of early C'Thun abilities, changes several Warlock and Priest cards, and revises Battlegrounds minions, Trinkets, and Dark Gifts.

Standard Balance Changes

Following the early temporary bans in Reign of the Black Empire, this patch shifts power from C'Thun's supporting abilities toward its late-game payoff. Other changes target Warlock combos, Priest quest requirements, and early Handbuff Death Knight boards, alongside improvements to several underperforming cards.

Dust Refunds, Event Cards, and Assemble

Spawn of C'Thun will become eligible for a full dust refund with Patch 37.2. A bug prevents its refund from being available in 37.0.2.

This is a one-time acceleration of their availability. Blizzard is also reviewing how missed event cards become available in the future. Additional free event cards supporting Old God decks are on the way.
