Zaahen Guide

Tips for Playing Against Zaahen

-Zaahen's dash (E) does 4% max health damage at rank 1, and goes up to 6%. This ability is a 10 second cooldown, so try to avoid it if you can.
-Playing safe early is probably gonna be your best bet.
-After a good spike, still be careful not to trade too long, otherwise he'll stack his passive. In other words, play it similarly to how you should play against Darius or Mordekaiser.

Oblivion Orb

Zaahen heals a lot, so Oblivion Orb is a fine option. Bramble probably works too if you're against 5 AD but I think typically Orb is just better.
Swiftness Boots

Swifties is great for engage and more importantly disengage. You don't wanna fight Zaahen for too long, so it's nice to make sure you're fast enough to get out!
Warmog's Armor

Haven't tried it myself, but I imagine Warmog's would be a nice 1st item here considering you'll be disengaging a lot. Heartsteel is probably perfectly fine too!
