Instantaneous Hex (3.5e Feat)
From D&D Wiki
Instantaneous Hex [General]
Your swiftness now extends even into your mastery over hexes.
Prerequisite: Unusual Swiftness 3/day.
Benefit: You may bestow a hexing as an immediate action. You may also initiate or change your hex aura as an immediate action.
Normal: You can only bestow a hexing, initiate your hex aura, or change your hex aura as a swift action.
Special: This feat provides a very powerful boost to a hexer by allowing them to counter certain forms of attack (among other uses) and thus a DM may choose not to allow it given the power level they are aiming to allow in their game.
