[_Kharbon_]

Soo
Duration 60, CD 70
Protection +30%

Well, for a mage, I wouldn't guess that boosting armour points would give a huge boost of defence. Perhaps, that if a conju has decent resists against a certain dmg type, the 30% protection bonus could help, but still, I'd rather go for Karma mirror, that returns the 30%...

However, I have to admit, that I didn't test this spell, so I might be wrong. From my point of view, it isn't worth it though. Conjurer has better defence spells to invest PP into.

For general defense, I use mind blank, energy barrier, steel skin (when required), and the self-healing spells.
Karma mirror is useful, only on high level though, since less than 30% is not much useful though.
The differences in CD/duration of mind blank and karma mirror make them situation based - sometimes they don't help much and you find out you just "wasted them", other times they save you from sure death..
