Buy Grand Charms with +1 to specific Skill Trees (Skillers). Essential for endgame builds, these provide massive damage/utility boosts. Choose your class, skill tree, and optional secondary stats like +45 Life (Baal GC) or 12% FHR. High-tier trees (Combat, Lightning, Java) cost more.
+45 Life Baal GCs: The godliest skillers. Can only drop from Baal in Hell difficulty. Extremely rare and expensive.
