Shroud of undeath

Shrouds of Undeath refers to a set of toggle forms available to Wizards in the Pale Master enhancements enhancement tree.

All shrouds cost SP to turn on, but persist through rests and entering quests, allowing this cost to be bypassed as long as the Wizard does not wish to switch or toggle forms. While undead, you have Heavy Fortification, are healed by negative energy, are unaffected by positive energy or repair effects, but take double damage from light effects, and you are considered undead rather than your original type for the purposes of most effects.

While in these forms, you may cast Death Aura, Lesser Death Aura, and Negative Energy Burst to self heal. You don't make Saving throw against helpful negative energy spells for half healing, and spells beneficial to Undead will no longer trigger spell resistance when cast on you by a Party member.
