Can Divine Infusion be cast on yourself and is the damage doubled on a critical?

Not to be confused with Divine Effusion...

You pour energy into the subject of your healing to empower
its attacks. If the next action you use is to cast harm or heal
to restore Hit Points to a single creature, the target then deals
an additional 1d6 damage with its melee weapons and unarmed
attacks until the end of its next turn. The damage type is void if
you cast harm and vitality if you cast heal.

You don't actually cast Divine Infusion on anyone. It is a spellshape, so it adds to the effects of the next spell.

Which could be a spell that affects yourself. So... effectively, yes. You can cause the effects of Divine Infusion to target yourself.

The damage that it causes is additional or bonus damage added to the Strike damage the target is already doing. Crits will double that damage.

Seems to be a good feat IF your able to strike twice in a round no?

Depends, vitality damage only works on undead so without negative healing using it is pretty situational unless you are fighting a lot of undead.

Even better to cast it on your Flurry Ranger ally.

But as MEATSHED pointed out, the damage type that it adds is situational.
