The biggest draw for Pale Masters is the self-healing in Undead form.
In order to make sure that I'm not going to jump into this Pale Master life unprepared, what Death Aura/Lesser Death Aura feats/enhancements/gear am I forgetting?
1) Negative healing amp gear (various - will take time to collect, but I'm not jumping into this life right away, so there's time)
2) Negative spell power gear
3) Negative spell critical chance gear
4) Wellspring of Power feat
5) Master of the Dead feat AND Master of Knowledge feat (since T5 is garbage in PM, so might as well take T5 Archmage)
6) Archmage T5 Arcane Supremacy
7) Extend metamagic feat since it's tedious to get all of the various feats to trigger together and then cast the Death Aura/Lesser Death Aura spells
What things am I missing that I'll want to have in place for a Pale Master throwing down those Auras? I'm leaving the gear generic instead of naming specific items because I want to be able to level through Epics with good auras and not just look at casting the spells at cap.
