Pale Master Template
I'll compare this to Dry Lich, seems easiest since they're both templates granted by PrCs meant for a Cleric.

Dry Lich: +5 LA; +3 CR
All HD changed to d12

Dessicating Touch, 5d6 dmg (save for half) + Con Drain
Aura of Despair: shaken for 1d4 rounds, 60'
+6 Turn Resistance
DR 10/bludgeoning and magic
Fast Healing 2
Immune to: dehydration, heat, polymorph (though they can use polymorph effects on themselves), and mind-affecting spells and abilities.
Unholy Toughness
Water Weakness
+2 Str, +4 Wis, +2 Cha
+8 to Hide, Intimidate, Listen, Move Silently, Search, and Spot
Suggested changed to Pale Master:
- Change Aura of Despair to just grant the Sickened condition and rename (this will also fit with the whole disease theme)
- Change stat bonuses to match Dry Lich (Int bonus seems out of place, Pale Master's aura is better than Dry Lich as well)
- Add Unholy Toughness
