You need 178 to take 0 damage.
I've tried the builds, and although it offers some interesting twists (Using intervention twice per recovery button, and immunity to death damage in general), the cons far outweigh the benefits.
Too much equipment and skillpoints are compromised in this process:
Death ward (3 skill points and an advanced skill slot)
Greater ring of death (Ring of unlife is a good choice, but this one? I wouldn't say. You're missing out on the Abbot ring here)
Shield of Life (Chitin shield offers the more desired stats: being spirit resistance. Clerics are the only class to not have access to stun immunity)
Nivarian cloak / Blessed Necklace (These would otherwise be substituted with the whopping +45 fire res and 1 endurance necklace, and either the +1 armor vorator cloak, or the +25 spirit resistance cloak)
Gauntlets / Pants / other equipment pieces, substituted to tolassian set (You could have blessed platemail, gauntlets of might, the 20mp gloves, Lionskin pants, many items with better stats than tolassian armor pieces)
All of this has to be let go, in order to gain 50 mp (worth 2 PER difference, at level 25) and 30 Spirit resistance (given extra 2 points of PER are invested, 26 spirit res). The rest of the equipment more than just covers for spirit resistance(not to mention other non-death resistances and armor rating), and yields similar amounts of mana.
So, in the end, you get to weigh between
Coolness, immunity to evokers & witches and a little bit more mana VS armor, resistances, skill points, and equipment freedom
The whole idea of keeping cursed artifacts turned me on, but sadly, it's simply too much to sacrifice, even to the sucker that I am.
TBH, i let go because the crown didnt show its glory on the character sprite.
