Boneharden

When this dweomer is cast, it causes bone to harden and become less brittle. Bones under the affect of this spell are harder to break than normal.

If used on a bone weapon, boneharden improves it, in effect removing the penalties the weapon would normally receive for both attacks and damage. If such weapons are magical, boneharden removes the normal penalty due to the material used (bone), making the weapon more effective, and consequently letting the dweomer cast upon the weapon take its full effect.

Boneharden spells are exclusive. Because they remove penalties rather than adding improvements, casting two boneharden spells has no more effect than casting one. The spell can't be used to add enchantments to weaponry.

When cast on a creature, the recipient gets a saving throw to avoid the effects of the spell. If the saving throw fails, the creature's bones harden, causing them to ache and the joints to swell. This gives the creature a -2 penalty to its initiative and its attack and damage rolls as it moves more rigidly and slowly. It also improves the creature's Armor Class by 2, however, since it effectively makes the creature tougher. Casting a second boneharden spell while the first is still in effect has no affect on the creature. The material components are a bit of bone and a tiny pinch of mortar.
