Iop (also known as Iop's Heart) is a class.
Iops are go-getting warriors beyond reproach! One thing's for sure: Iops know how to use their weapons. They need to jump in a brawl at least once a day just to feel alive. Their impetuousness can make Iops the best of knights, but also the worst!
Iops are often referred as idiots, dumb or even brainless in some item descriptions of Dofus (Kriptonite, Evil Dandelion Flower, Kluh's Boots and Dark Treechnid Root Wand as some examples). This is related with its class characteristics and skills, which can be related to the stereotypical strong, but dumb warrior of many games, TV shows and RPGs in general.
