These hexagonal, cold iron bands are sized to fit over the biceps and bear various arcane runes.

Hexblades (CW 5) rely on these items to enhance their curse power and their combat prowess. While worn, hexbands increase the save DC of your hexblade’s curse by 1. This is a continuous effect and requires no activation.
In addition, when you activate your hexbands, you can add your Charisma bonus (if any) on weapon damage rolls you make against any creature currently affected by your hexblade’s curse. This benefit lasts for 1 round, and this ability functions five times per day.

Prerequisites: Craft Wondrous Item, eagle’s splendor.
