Does Catalyst make Poison damage pierce armour, and does it hit every adjacent hit point?

Question

Accepted Answer

Yes. Poison damage is piercing, and Catalyst resolves it all at once, so each adjacent undamaged hit point takes 1 piercing damage. The initial wound from the poison cube is not piercing.
