Orb of Upheaval

Rerolls every modifier that is not bound (rarity, item level and quality stay).

What it does

Rerolls every modifier that is not bound (rarity, item level and quality stay).

Only an item with a rarity; bound modifiers stay.

Uniques, ruined items and stacks are refused; the crafting bench shows what an orb would do before you use it.

Used directly: Use with on the orb, then click the item.

Rerolls the modifiers of a Rift Key (one to three new ones).
