Hunter's Mercy
(Spell Compendium, p. 117)Transmutation
Level: Ranger 1,
Components: S,
Casting Time: 1 standard action
Range: Personal
Target: You
Duration: 1 round
Your eyes glow red, but you see the world as normal except when you look at your target. A small glowing dot reveals the creature's weakest point.
This transmutation makes a bow strike true. Your first hit with a bow (not including crossbows) in the next round is automatically a critical hit. If you don't hit in the round following the casting of this spell, the effect is wasted.
