With tash these make excellent Command of Druzzil pets. The ones that are immune to changes in run speed seem to be quite a bit stronger than the others. Hasted, it was able to tear through 4 or 5 slowed golems before it got low on health. (The regular crawlers can only manage about 3 golems.) I have 262 buffed CHA and TD2, and charm is fairly reliable for me (although it's bound to occasionally break at bad times). Just have SoE and sit back far from the fight, and you'll be fine.
