How to Build Ares (Arena)

While Ares is a guardian and can do a great deal of tanking, that is not my particular style. I find that Ares helps excel and lead his team to victory best through use of his damage exploits. Not to mention I tend to out damage everyone on my team.

How you build Ares has to be situational in order to get the greatest possible start.
I have basically the same build for both circumstances, the only differences is the order you build items in.

This video should adequately address my approach - Play Video

In order to put out the highest damage potential, you are going to want to level your chains first (1) and his flames second (3)
His buff for defense (2) can be altogether ignored as it simply hinders Ares.

Pros -
Great damage
Innately tanky
Powerful ultimate
Many different play styles
Makes opponents vulnerable for team
Great one person focus damage

Cons -
Has no escapes
Can't handle a group of 3 or more easily alone

While you won't be spending too much time taking out creeps, don't ignore them if your team is low on health and needs help. Use your flames to do what damage you can, however their only true minion usage is for clearing a camp or taking out a siege tower. Still, don't fully ignore minions.

When your ultimate is up, make sure you keep track of who has their actives up and who doesn't.
Try and grab the largest group of enemies clustered together as possible.
You are going to want to pop their beads and run if you are alone, or pull them and place chains if you have an ally nearby.

I've never done a guide before, so I'm sure this was infantile.
If there are any truly outlandish peculiarities, notify me and I will look into them.
Best of wishes!
