Clicky

A clicky is a magic item that, when activated, casts a spell or effect.

Clickies usually come with a number of charges/rest equal to either 1, 3 or 5, and cast a spell at the minimum caster level required to obtain it (with the exception of some static items).

Clickies can be any armor or helmet but are most common on rings, belts and other accessories.

Not all spells can be found on clickies, but a number of useful ones can be found, if you farm enough.
