Aggron Stonebreak the
Ogre Magi is a roaming support hero that requires nearly no items to be impactful in the game. His skills can be leveled in a variety of ways; depending how when your carry comes "online", meaning ready to start engaging in team-fights. If ready in the mid-game, max out
Bloodlust when possible, otherwise, the
Fireblast/
Ignite combo works very well in team-fights to wear down enemies. Items such as
Urn of Shadows and
Force Staff help alleviate the mana demand of
Ogre Magi's abilities as well as give him further mobility to either surprise foes or escape safely; mobility is
Ogre Magi's bigger issues and waddling as he does surely doesn't help.
Unrefined Fireblast has been changed to cost 60% of your
current mana, so there isn't this problem anymore. If you're going to
play 
Aghanim's Scepter
