Durkon - How powerfull?

[terenes]

During his fight against Malack it was hinted that Durkon is higher level cleric due to lack of adequate challanges for mid level cleric-vampire.

Now Durkon is vampire himself, so his level would be 14+8 = 22, and he would be stronger than Malack. This can implicate that is also stronger than Tarquin.

Let's check his stats (from clas and level Geekery thread):

Lawful Evil, Dwarf vampire male non-theistic (forum) Cleric 14 (based on spells cast in a day).
Str 20-25 (can carry Vaarsuvius, can't carry Roy; +6 as vampire).
Dex <14 (dex penalty, SSDT; +4 as vampire).
Con n/a (undead).
Int ~12 (no evidence; +2 as vampire).
Wis 19-25 (required for 7th-level spells, and to lose his best 7th-level spell to Enervation; +2 as vampire).
Cha <14 (low modifier; +4 as vampire).

With addition of race abilities (d12 hp dice, energy drain) and spell buffs (some Thor's might equivalent) doesn't it make him strongest revealed melee fighter in ootsverse (MItD capabilties are unknown) and second strongest character after Xykon?
