About the Game
Item effects depend not only on stats, but on trigger point direction and linkage conditions from positioning. Change positions to alter frequency and routes, creating your own chain rhythm.
Items vary in shape and size. Weigh active triggers against passive effects, carefully managing limited slots to find the optimal combination.
Each hero's exclusive items build different systems. Multiple tactical combinations meet 20 difficulty levels and unique mechanic monsters, relentlessly testing the depth of your builds.
