Shield spikes and the bashing special ability

[shilsen]

A shield with the Bashing special ability "deals damage as if it were a weapon of two size categories larger" (DMG 218). Shield spikes turn a shield "into a martial piercing weapon that increases the damage dealt by a shield bash as if the shield were designed for a creature one size larger than you" (PHB 125).

Do these effects stack if both are applied to a shield? Would a medium light spiked shield with the bashing ability do 1d8 dmg or 1d6?

IIRC, the bashing enhancement does not change anything about the spikes at all. See Hyps post in some of the other shield spike threads right now.

Base damage for a light shield is 1d3 isn't it? a Bashing enchantment would make that 1d6 bludgeoning, shield spikes would make it 1d4 piercing. Sounds silly? you're attacking with the spikes, not with the shield. Also the spikes aren't magical, and would have to be enchanted themselves.
