Deep Crystal

[Yogibear41]

Does the extra damage from spending power points on a deep crystal weapon get multiplied on a critical hit?

[Rubik]

Does the extra damage from spending power points on a deep crystal weapon get multiplied on a critical hit?Unfortunately, "Extra damage dice over and above a weapon’s normal damage is not multiplied when you score a critical hit." The deep crystal entry doesn't give an exception for this. So, no.

[Emperor Tippy]

No, Deep Crystal is an extra 2d6 damage and extra damage dice are virtually never multiplied on a critical hit.

Critical hits generally only increase the base weapon damage and flat bonus damage (i.e. a Strength bonus or a Collision weapon as examples).
