Usage affixed or held in 1 hand

Bulk L

This magical banner has an intricately embroidered pattern of shards and cracks across its surface, almost like a broken mirror. Though it always feels dry to the touch, this banner from a distance gleams red as if slightly stained with the blood of your enemies. While holding a banner of piercing shards, you can use the following ability.

Activate—Shards Seek Wounds (concentrate)

Frequency once per minute

Effect Shards of sharpened glass violently shoot out from the magical banner into the newly opened wounds of a nearby enemy. The magical banner deals 1d4 persistent bleed damage to any enemy within the banner's aura that has been dealt damage since the end of your last turn.
