Maybe this is more like it, at least it's straight forward this time:
Taurog's Armory (60 Piety):
Grants you Skullpicker, Wereward and Taurog's Totem in exchange for 3 Max MP (can't reduce below 1 MP)
Skullpicker: Might effect at full MP
Wereward: Immunity to Corrosion and Weakening at full MP
Taurog's Totem: Usable: grants Deathprotection and Manaburns you. One charge, can't use when mana burned.
Body over Mind (50+50 Piety)
Sacrifice 5 Max MP, gain +1 BaseDamage/LVL and +10% both Resists
(can't reduce below 1 MP)
Crippling Onslaught (40 piety): Slow effect on attack while having full MP.
Get off my lawn (50 piety)
Decreases the cost of PISORF by 1 MP. You no longer take punishment by casting PISORF.
Unstoppable Fury (35+15 Piety):
Reloads Taurog's Totem so you may use it again.
All boons technically say: Don't use MP or we will be gone. Using the Deathprotection shuts off most of your boons too so keep your potions to heal up. There is something in for PISORF mages as well. And kind of the opposite of the Flames boon.
Unique: Permanent Might, Slow on attack, better PISORF
Downside: Human Berserkers/Rogues of Taurog are pretty much OP
I hope at least one or two boons of all the iterations will be something that brings the devs to good ideas to make taurog more interesting.
