Paste your Raidbots droptimizer URLs to find out where your Voidcore bonus rolls will give you the most DPS.
Rankings are based on simulated DPS gain. Bad luck protection (no duplicate drops per slot) is not modeled by Raidbots — if you already own the best item from a boss, your actual value will be lower. Voidcore cost: 1 per M+ dungeon, 2 per raid boss.
