Penetrating Whetstone

Source Monster Hunter's Handbook pg. 29
Aura moderate evocation; CL 8th
Slot none; Price 2,000 gp; Weight 1 lb.


This whetstone is made from finely worked obsidian. Sharpening a blade with this whetstone requires 15 minutes of work and grants the weapon the ability to ignore up to 3 points of natural armor for its next five attacks. If the target of the weapon’s attack has a natural armor bonus of less than +3, the weapon deals 1 additional point of damage for each point of natural armor below 3 the target has. The process of honing the blade shatters a portion of the whetstone’s enchanted obsidian, dispelling its magic and turning it into a mundane whetstone afterward.


Requirements Craft Wondrous Item, keen edge; Cost 1,000 gp
