Idle Backpack Survivor: RPG

⚔ **YOUR BACKPACK IS YOUR WEAPON.** Every sword, ring, gem and potion you place changes how your hero fights. Combine adjacent items to unlock devastating synergies, then watch the auto-battle unfold against waves of enemies. The deepest idle roguelite RPG of 2026. 🎒 **BUILD. FIGHT. EVOLVE.**
Drag items into your magical backpack. Position matters — a Sword next to a Ring deals more damage. A Shield next to a Helmet grants extra HP. Discover hundreds of synergy combinations across 5 unique biomes and 60 increasingly brutal waves of monsters.
