How do I model spiked armor/martial arts

[mytrustyd20]

Hola!
I have a race of hulking barbarian ogre dudes that use grappling and throws as their primary fighting style.

My pc is playing one and wants to create (over time) modifications to his light armor that has spikes and such to increase the damage of his attacks.

How do I "build" this with Hero?

Example, is it a hand to hand attack (+d6 maybe) that adds to specific martial arts attacks?

HKA, OIF (Armor, -1/2)
Possibly with "Must Follow Grab" -1/2

That's for spikes.

You could also build it as a Damage Shield (+3/4?), which would require Continuous (+1), and most likely Reduced END (0 END, +1/2) & Persistent (+1/2), Only When Grabbed or Slammed (-1/2). That would represent armor spikes that both add to damage and if say a big dragon picks one up.

Offensive Damage Shield. It will be expensive, but unless youre making them pay points for gear it doesnt matter.

You may want to consider requiring a Familiarity to use spiked armor correctly without hurting ones' self.
