Short Spikes
Short spikes are an inch or two long. They make it difficult to move, but provide a few benefits.
Any creature grabbing or grappling the wearer of armor with these spikes take 1d4 damage each round - The same goes if the wearer grabs or grapples an opponent. Creatures that make touch attacks or Unarmed Strikes against the wearer must make a reflex save (DC 22) or take 1d4 damage as well.
The gauntlets that come with this armor are also automatically Spiked Gauntlets as well, though the spikes can be removed if regular gauntlets are preferred.
It costs a further 8 uV to add spikes to an existing suit of armor - the price listed is the additional price for a suit made originally with spikes.
Armor can have either these OR Long Spikes - never both.
