Each week Dominic Hobbs brings you Blood Pact. "You gotta be a moron... you gotta be a moron to wanna be a fighter. " ~ Rocky Balboa
Over the last few months Blood Pact has had a mini-series running to introduce the various demonic accessories. "Meet the Minions" has covered imps, voidwalkers, succubus and felhounds as well as infernals and doomguards. Along the way we have also covered such game-play lessons as pet-use, threat, crowd-control and mage-hate. So that only leaves the one minion to cover, the mighty felguard.
Unlike almost all the other minions there is no quest to gain the ability to summon the felguard -- you simply pop a point into the talent and this demonic knowledge is dropped into your brain. The talent is currently on the ninth tier of the demonology tree, so you will need to be level 50 before you can learn it. Even at level 80 you will need to invest almost 60% of your talent points into demonology just to reach it, leaving little room for anything in the other trees. Because of this the felguard is pretty much only seen with demonology-build warlocks. Hybrid builds were popular at the start of Wrath, but changes to spell mechanics have meant that they are rarely used these days.
