I have cazac thule and have found it fantastic for admittedly uncommon situations.
1) i use the charm miracle/spell which is like the charm undead one we get anyway but will charm live mobs (doenst charm everyone and doenst work in archadescism) but for example i solo'd the magolemus at level 70 by charming one of the fire giants to help my pet.
2) the other one i use - cant remember name as at work just now) basically roots then slows mob to 10% speed for 60 secs - which can be great for named that are just that bit too tough normally.
just pointing it out for those who haven't tried cazac thule. i dont use fear cape anymore as there are better capes these days.
