Oversized Spikes Added to Armor

[Adm.Venge]

I was talking with another player about the possibility of adding "inapropriately sized" spikes to armor, and we decided it might be something to ask about on the forums.

The description of spiked armor says it "counts as a light weapon" when used to make a regular attack. Does this mean it is always a light weapon, regardless of size (similar to the rules for "inappropriately sized" firearms)?

It also appears on the weapon's table as a light weapon (for appropriately sized creatures). Does that mean it is a one handed weapon if one size larger, and a two handed weapon if two sizes larger? If you are wearing spiked armor that counts as a 2 handed weapon, could you wield it as such? Would you get 1 1/2 Str mod to damage when making a normal attack?

Or is it not possible to add "inappropriately sized" spikes to armor?

The weapon is "spiked armor", so damage goes by the size of the armour, not the size of the spikes.

Huge-sized spikes on Medium-sized armour would be a bit awkward anyway.

I'd say this is a gray area fully within the realm of DM jurisdiction.

However, I see nothing wrong balancewise with allowing 1d8 spikes on an armor, when it comes with a -2 for using wrong sized weapons. That said I'd much rather apply it to ACP instead, but then we're completely within house rule territory.
