You know, if you don't count slayer property, if i see 3 succubus tyrants around i use my champ axe becasue it's all what i need whirlwind, triple leech, whatever. About tactic, there is not much you can do but casting melee spells... thats all. Killing them with mage spell or pets is another story.
Btw, Sturger if you don'T mind check the november quest succubus area and lure 3 of tem and try to kill em, and notice me the what tactic you used.
