Bloodwind (Longbow +2)

This bow was forged in a future that never came to be. Somehow, it has ended up in your hands.
The cruel and unusual design of this bow causes its arrows to inflict truly grievous wounds. If this bow ever deals damage to a creature, that creature continues to take an additional 1d6 damage at the start of its turn for each arrow that hit it. This effect lasts until the creature is healed.
