With maxed warmog's, health is over 5k. take that health and apply FoN's passive and then add an additional 15% healing/regen increase from spirit visage and volibear regens over 200 hp per 5 sec. in combination with his passive(which is also boosted by spirit visage) volibear is almost hard to kill. boots of swiftness combined with FoN and rolling thunder make him very fast. excellent for ganking and harassing while building. for best attack results, use rolling thunder> majestic roar>basic attack>Basic attack>frenzy. if enemy is tough, use surge/thunder claws first. if you get in trouble or ganked, flee with ghost and rolling thunder.
