Felsteed (warlock ability)

Felsteeds are summonable warlock mounts and the name of the spell to summon this mount. Unlike the epic Dreadsteed you do not need to have the riding skill trained in order to learn/use this mount, so once you learn the spell, you have the training.

With The Codex of Xerrath (ability) the mount changes the color of its flames to green.
