It's a tank, it's not easy to kill, especially with the buff, Ares play that you hit the chain and then release the flames, thanks to the chains, every enemy won't escape you even with a spell (if they don't have beads) and the flames do more dmg with the buff, protect yourself, allies and minions, in in the middle and late game your team relies on your ultimate, it's the start of the fight, you grab the enemy and pull him completely towards you and he's still stunned for a while, at that moment chain grabs are good so they don't run away and flames with a buff and your team will take care of the rest in by that time you already have a clear win
