Mystic Orbs

Mystic Orbs add a modifier to an item in the Horadric Cube. In the game every one of them is called Mystic Orb; its description says what it adds, which is how the table names them.

How to use them

Cube one orb with the item to add its modifiers.

The orb is consumed; the item keeps its other modifiers.

Use only the item kinds listed below.

Weapons and armour must be non-ethereal.

Each use adds +2 Required Level.

Listed effects are for non-honorific items unless stated otherwise.

Honorific items double these modifiers at the same required-level cost; proc skill levels, poison duration and nonnumeric effects stay the same.

The orbs

Making an item honorific first doubles what orbs add to it. See also Unique Mystic Orbs.
