Don´t think 5 monstercompanions are enough? Well, equip that monstersummoning wand and cast Simulacrum. Now you can let your clone spit monsters till he bleeds!! It´s rather fun to have 30 ogres chanting "Me will crush you, crush you to goo!" at the same time. Looking for the spell that gives you most bang for the buck? Try hasting those 30 ogres.......;)

That is a loophole in the game? Monsters summoned by a simulacramed char aren't limited? Hmm.
