Soul

energy, rare

Soul damage is an esoteric form of offensive strike which assaults the target creature's spiritual energy, rather than its flesh. Like force damage, soul damage deals equal damage to corporeal and incorporeal creatures. Furthermore, soul damage works equally well on undead as it does the living, since nearly all undead have some animus tethered to them. Constructs and other targets which have neither soul, animus, nor spirit, are typically immune to soul damage.
