You can basically attack your own faction or non hostile combat pets (to annoy ppl) with this lil' trick.
Get a Warlock, (Ofc) then Summon your Succubus, and make all the attacks non auto and make it cast Seduction on the target (works on players too) and it will start channeling, after the spell has finished channeling it will run after it and start attacking it for about 300 damage per swing,
Pretty useful for annoying ppl in the malls of Funservers. (Make sure its not a druid with thorns or Paladins with Retributional Aura or Mage Fire Shield )
Enjoy.
