Poker hands deal damage. Spire cards spend energy. Survive Vantom as Ironclad or Silent.
Choose Ironclad or Silent and take on Vantom in a replayable solo boss duel inside Balatro. Build poker hands to deal damage, then spend energy on a separate Spire card hand to attack, defend, draw cards, apply vulnerable, weaken attacks or stack poison.
Two characters, twelve Spire card definitions, eight-card poker hands, two boss phases, visible enemy intents and same-seed replay. Solo only in this first release; co-op is not included.
You need both Balatro and a Steam installation of Slay the Spire 2 on Windows x64. Melty installs Lovely automatically. The mod discovers Spire 2 in your Steam libraries and loads real portraits, card art, boss art and names from your copy while it runs. No game assets are shipped. Card values and the boss encounter are adapted for this mashup.
Tested locally in Balatro 1.0.1o with Spire 2 v0.107.1: 33 assertions and six full simulated fights, plus real mouse input and gameplay capture. Melty's install recipe passes its one-click check; installation through the Melty app is still to be verified.
