These ornate, silver-filigreed black gloves are topped by silvered palms and fingertips that regulate arcane energy for increased casting efficiency. They are thin and mobile enough to not interfere with the somatic component of the casting process. When worn, the arcane cestus allows a spellcaster to make melee and ranged touch attacks involving his arcane spells at an enhancement bonus equal to the cestus' bonus. The magic of the cestus also applies to other arcane spell-like abilities, such as a warlock's invocations.
