ARROW OF CURE LIGHT WOUNDS
When this otherwise normal +1 arrow strikes a target, it does no damage. Instead, the target is affected as if by a cure light wounds spell, which cures 1d8+1 points of damage. If such an arrow strikes an undead target, the creature is entitled to spell resistance and a Will save (DC 11) for half damage.
An arrow of cure moderate wounds cures 2d8+3 points of damage and has a save DC of 12.
An arrow of cure serious wounds cures 3d8+5 points of damage and has a save DC of 13.
An arrow of cure critical wounds cures 4d8+7 points of damage and has a save DC of 14.
Caster Level: 1st (light), 3rd (moderate), 5th (serious), 7th (critical); Prerequisites: Craft Magic Arms and Armor, cure light wounds (light), cure moderate wounds (moderate), cure serious wounds (serious), or cure critical wounds (critical); Market Price: 107 gp (light), 607 gp (moderate), 1,507 gp (serious), or 2,807 gp (critical); Cost to Create: 57 gp + 4 XP (light), 307 gp + 24 XP (moderate), 757 gp + 60 XP (serious), or 1,407 gp + 112 XP (critical).
So…
(50) Arrows of cure light wounds: 5350
Thus the curing effect is not a +1 bonus, but instead a flat 3,000 gp.
So that would be spell storing arrows +1 of cure light wounds for 7350 gp.
