Demon Queen's Crown

Demon Queen's Crown is a Legendary relic that doubles your Power slot limit from 3 to 6, fundamentally changing how you build your deck. Powers are among the strongest card types since they provide persistent effects all fight, and normally the 3-slot cap forces hard choices about which to keep. With this crown, you can stack complementary powers like damage scaling, draw, and block generation all at once.

The relic pairs exceptionally well with Mirror of Bonds, since having six powers that each trigger twice creates overwhelming compound value. It also enables greedy power-heavy decks that would otherwise be forced to overwrite crucial powers. The main downside is that loading up on Powers means fewer attack and block cards in your deck, which can leave you vulnerable in the early turns before powers are set up.

Cracked Hourglass helps by tutoring your key powers into your opening hand. Priority: always pick when offered; doubling Power capacity is one of the strongest effects in the game regardless of build.
