Chubby Arena Turtle

Starts out building defense, maximizing assists and gold with mystical mail, then HP5 aura and maxing HP5/MP5. Once you get Kusari then you stay near your warrior or hunter to max their attack speed, and then you build the Mantle to max out your protections and reduce cooldown. Thorns complement shell spikes and emblem of terror prepares enemies for death.

You could use blink rune instead of one of those two relics if you want to be able to sneak behind enemies a little easier. Usually I just wander around a pillar and sneak into the midst of the enemies and grab one. Or I just walk into the enemies and ult, then grab a weak one and bring them back to my team.

This build is kind of an infinite life build, it's meant to keep your HP and MP up so you can stay out of the fountain for as long as possible while also helping your allies keep their HP up and helping a warrior or hunter to max their attack speed.

You probably won't get a ton of kills with this build, but you will upset your enemies and you will get a lot of assists. Start out shooting your turtle through the minions, getting as much gold as possible, and causing chaos on the battlefield to give your allies chances to get some kills. Once you build the mystical mail you can just walk near minions to get easy assists even if you dont hit them with a basic attack, so at that point you should start saving all your abilities for enemy gods. Try to hit them with the turtle every time, don't just shoot him out and let him walk to enemies if you can help it -- he does a lot more damage if you hit the enemy with them than if he has to run after them.

Once you get sovereignty make sure to stay near any teammates with low HP so they can build their HP back up. You should also be fat enough at that point to just get between an enemy and an ally if your ally is in trouble and take the hits while your ally escapes.

When a fat turtle comes at you in arena you only have two choices. You can waste your abilities on him and then watch him run away while his allies murder you... or you can leave him alone while he collects gold and prepares to push you to his allies for a prompt death. Be the fat turtle.
