What to do about Ermor ....

[Pickles]

Quoting Lintman
"With 3S, the golem can teleport from the lab to a distant province, and in battle can cast Body Ethereal, Astral Shield, Personal Luck, Twist Fate, and Astral Weapon before stomping away."

Hm you have not actually done this I take it - those spells cost over 100 fatigue with the 14 casting fatigue from armour.
I have one of these in a game at the moment he has
Accursed Shield, Main gauche of parrying, Wraith crown, Wings, boots, lucky charm & bracers of defence. The items duplicate his spells of course & he is a raider not a full on SC & he has yet to really take part in a proper battle.
I am Ulm with Forge of the Ancients & the items were a song. He has good prot & defence for a Golem but is magically a bit vulnerable I suppose - this has not come up in games I have played yet.
I just lost a differently equipped one when it fatigued out (It was an error to leave the Army with the relief casting witches)
