These armbands are made from red gold studded with tiny rubies. Dozens of needlesharp spikes extend slightly from the inside of the bands.

Each time you don bands of blood rage, they deal 1 point of damage to you. This damage can’t be healed as long as you wear these armbands.
When you activate bands of blood rage, you and any willing ally within 30 feet can enter a blood rage that lasts for 5 rounds.

This blood rage can’t be ended prematurely except by unconsciousness or any effect that would end a rage (such as a calm emotions spell). Unlike a barbarian’s rage, the blood rage doesn’t limit your actions in any way.
While in a blood rage, a character gains a +5 morale bonus on melee weapon damage rolls. However, each affected creature also takes 5 points of damage each round at the end of its turn as its own body suffers under the strain. If you are a sorcerer or you have the dragonblood subtype (see Races of the Dragon or Dragon Magic), you also gain a +5 morale bonus on damage with your arcane spells while in a blood rage created by bands you wear.

Bands of the blood rage function three times per day.

Prerequisites: Craft Wondrous Item, rage, sorcerer or dragonblood subtype, possession of a piece of the set.
