The new Psi Warrior Fighter subclass has the feature Psionic Power which has the following option:

Psionic Strike. You can propel your weapons with psionic force. Once on each of your turns, immediately after you hit a target within 30 feet of you with an attack and deal damage to it with a weapon, you can expend one Psionic Energy die, rolling it and dealing force damage to the target equal to the number rolled plus your Intelligence modifier.

Is this ability affected by critical hits like a Paladin's Divine Smite or does it deal extra damage independent from the attack?

    \$\begingroup\$ Does this answer your question? How does extra damage work for critical hits? \$\endgroup\$ Dec 7, 2020 at 3:52
  • \$\begingroup\$ @GreenstoneWalker The reason why I asked this question is because the phrasing of Psionic Strike is notably different from other "extra damage" features. Divine Smite for example says "when you hit a creature" as opposed to "immediately after you hit" and clarifies with "in addition to the weapon's damage." Unlike extra poison damage, however, Psionic Strike asks for no saving throw and, in its flavor text, it is described as "propel[ing] your weapons with psionic force" \$\endgroup\$

  • \$\begingroup\$ I think Psionic Strike is sufficiently distinct in its phrasing to warrant its own answer because it is unclear whether Psionic Strike falls within "the attack involves other damage dice" \$\endgroup\$

The damage die is not doubled

Critical hits double the damage dice on the respective attack. That means if an attack deals an additional ndx damage due to a feature that n becomes 2n.

The feature in question does not add the damage to the attack, however: It does not say "deals an extra psionic energy die of damage" neither does it say "rolling it and adding the value to the damage" but rather "rolling it and dealing damage". This indicates that the damage is not part of the attack and hence not doubled.

Another indicator is the templating which makes the extra damage contingent on dealing damage and not just on scoring a hit, implying that at the time the die is rolled, the determination of the attack damage is already completed.

The counter example is College of Swords Blade Flourish feature which triggers

if a weapon [...] hits a creature

and you can use the bardic inspiration dies

to cause the weapon to deal extra damage to the target you hit

where the templating implies that the damage is extra damage of the attack and that the extra damage gets determined after the atatck roll rather than the damage roll.


The damage die is doubled

Reading the critical hit rules, we get this bit:

If the Attack involves other damage dice, such as from the rogue’s Sneak Attack feature, you roll those dice twice as well.

That is why you don't just roll the weapon damage dice on a critical hit.

I would say that the Psionic Damage is "involved" in the attack.

So yes.

While the wording of this damage die is different than other damage dice boosts, all that matters is if the damage dice from it is "associated with the Attack".
