An idea born from a certain bloody computer game:
Serrated Edge
[Melee Weapon Modification]
Cost: +20% base weapon’s cost (bladed weapon only)
Attack Modifier: base weapon’s attack modifier -1 (see below)
Description: Giving a bladed weapon a serrated edge means slashes with it will more likely inflict painful, if somewhat superficial, injuries on creatures not wearing armour, though the weapon will also more easily snag on actual armour, making it more difficult to actually cut deep.
Special Rules: When making attacks against a living character who does not get an ARM bonus from worn armour, this weapon does not inflict an additional attack roll penalty and gains +1 POW.
On a critical hit with this weapon against a living character who does not gain an ARM bonus from worn armour, the attacker may spend a feat point to cripple the aspect damaged first by this weapon’s damage roll for one round (If the target character does not use a life spiral, they suffer -2 STR for one round instead).
Special: Double-edged bladed weapons can have one serrated and one non-serrated edge, though this does not affect the cost of making the weapon. Switching between the edges requires the wielder to adjust their grip by using a quick action.
Comments welcome, as usual.
