Synthesis vs Alchemy
Synthesis upgrades gear tiers; Alchemy funds your runes. Using the wrong mode costs hours.
When to Alchemy
- Early game until second and third hero slots are unlocked.
- When inventory is full of duplicate whites/greens.
- When you need gold for Rune nodes immediately.
Synthesis Rules
Nine items of equal rarity → one item of the next rarity (random). If your Cube synthesis level is too low, high-level gear can downgrade on failure — this is a level gate, not a random bug.
