Soulbows who are smaller or larger than Medium create mind arrows identical to arrows shot from composite longbows appropriate for their size, with a corresponding change to the arrow's damage (see Table 7-4 and Table 7-5 in the Player's Handbook). For instance, a Medium soulbow materializes an arrow that speeds toward the specified target, and if it hits, deals 1d8 points of damage (crit ×3) plus extra damage equal to the soulbow's Wisdom modifer. The bolt is identical in all ways (except visually) to an arrow shot from a composite longbow.
You must have one hand free to create and project a mind arrow. If your base attack bonus is high enough to grant you multiple attacks, you can create multiple mind arrows as part of an attack. Mind Arrow (Su): As a free action, you can create a semisolid arrow composed of psychic energy distilled from your mind.
