Pathfinder 2e Action / Feat: Spirit Rage

Trigger You use the Rage action on your turn.

Description When you are raging, you can increase your damage from Rage from 2 to 3 and deal negative or positive damage, instead of the normal damage type for your weapon or unarmed attack (choose each time you Rage). If you choose to deal negative or positive damage, your weapon or unarmed attack gains the effects of the ghost touch property rune, which makes it more effective against incorporeal creatures, and your Rage action gains the divine and necromancy traits, plus negative or positive, as appropriate.  
Applications  When using spirit rage, increase the damage from Rage from 3 to 7. If you have greater weapon specialization, instead increase the damage when using spirit rage to 13.
