Acid Grave Sheath

This black leather sheath adjusts itself to any bladed weapon you bond it with. Bonding a weapon takes 1 minute. Dismissing a weapon is an action.

Any non-magical or non-treated weapon starts to corrode at a rapid pace while sheathed. Such a sheathed weapon gets a -1 penalty to damage for every 10 minutes inside the sheath. When a weapon reaches a -3 penalty it is destroyed.

When unsheathing a weapon, that has been sheathed for at least 1 turn. It is doused in acid and the next attack made with that weapon deals an additional [roll]1d8[/roll] acid damage.
