Character concept: A custom character mod for Slay the Spire 2. A deceptively ordinary-looking survivor with uncanny reflexes and an ability to cheat death — calm exterior, absurd instincts, fights using improvised everyday objects rather than traditional weapons. Build paths (must support at least 3 distinct viable playstyles, not one linear strategy): 1. Death-Loop path A "Resolve" meter builds during combat as the character takes damage or plays loop-related cards. Resets each fight (per-combat, not stockpiled). Once full, it can be spent to survive a lethal hit: 1st use in a run returns ~50% HP, 2nd ~25%, 3rd ~10% (decaying with repeated use). Each use also permanently reduces max HP for the rest of the run — a real trade-off, not a free pass. Dedicated At...
