Hero-dric Cube Guide
The Hero-dric Cube (a nod to Diablo's Horadric Cube) unlocks at hero Level 4 and is your crafting hub.
Alchemy — turn junk into gold
Alchemy converts unwanted items into gold and Cube XP — your main early gold source. Use Auto-Fill, but Alt+Click to lock keepers first.
Synthesis — should I merge gems/items?
Synthesis combines 9 same-rarity items into one of the next grade (random, can skip tiers). Merge duplicates you won't equip; don't feed items you still use.
Crafting — early accessories
Crafting builds random gear or accessories within a level range — the best early source of accessories.
