Blue Candle

Blue Candle is an uncommon relic that allows unplayable Curse cards in your hand to be played. When you play a Curse, it deals 1 damage to you and is then Exhausted (removed from play for the rest of the combat). Curses are normally deadweight cards that clog your hand, so the ability to clear them with a small HP cost is a meaningful deck management tool.

Blue Candle transforms Curses from liabilities into manageable nuisances. Instead of drawing a Curse and being stuck with a useless card in your hand, you can spend 1 HP to exhaust it and effectively draw the next card. In runs with many Curses (from Cursed Key, Calling Bell, or events), this dramatically improves deck consistency. It synergizes with Rupture (taking damage gains Strength), Darkstone Periapt (Curses give Max HP), and other cards and relics that benefit from taking HP damage. Du-Vu Doll and Blue Candle are an interesting pairing: accumulate Curses for Strength, then use Blue Candle to clear them when needed.
