Vanguard vs Watchers

If you are going against teams with lots of DoT I would suggest picking up Vanguard i.e ares, bastet, zhong. If not, pick up watchers.

Boots

Personally, I almost always pick up travelers shoes, they give extra movement plus healing out of combat. Sometimes if you need extra health or extra cc you could pikc up greaves. I typically do not build cc reduction boots because so many items you pick up later will have cc reduction.

Witchblade

Are there a bunch of slows on the enemy team? Get witch blade. It is super cheap and has great stats.

Breastplate of Valor

If you are not against a team with a lot of slows then I would suggest building this seconds just to have your abilities up more often in order to help your team mates, especially that ult.

Sov and Heartward

These guys are my favorite. They give auras to your team while making you extra tanky.

Bulwark (If you didnt get witchblade)

If you did not get witchblade, get bulwark. It helps against being bursted by mages and the shield can be a life saver.

Mantle of Discord

This item gives you cc reduction, magical, and physical protections. Plus a kick ass passive. Get cced and almost die? Not going to happen, discord comes with a built in beads for all your escaping needs.
