Lethality completely breaks Kayn
Honestly, fuck building bruiser on Rhaast, just go youmuus-DD--duskblade-Situational defense Can even take lethality marks and quints if you want.
You literally 2 shot their entire team, and since you do so much damage, you heal a fuckton, you need positioning , but given the chance you literally dick their entire team. No need for Cleaver when you do %damage, no need for More damage when with lethality you already 2 shot the squishies anyways. I love the champ, but this build is actually stupid. Reminds me of when crit worked on camille's Q.
