Armored Mage (Ex)

Type of Feat: Class Specific
Prerequisite: Warlock 1

Because the somatic components required for warlock invocations are relatively simple, a warlock can use any of his invocations while wearing light armor without incurring the normal arcane spell failure chance. However, like arcane spellcasters, a warlock wearing medium or heavy armor or using a shield incurs a chance of arcane spell failure (all invocations, including eldritch blast, have a somatic component). A multiclass warlock still incurs the normal arcane spell failure chance for arcane spells received from levels in other classes.

Use: Automatic.
