Warlords blood lust is the optimal keystone for Irelia right now due to the nerfs on fervor and the other keystones not being best suited with her kit , plus Warlords being buffed in season 6 a few patches ago make is a better choice right now . Thunder Lords , CotC , and Fervor can be viable choices . IMO , CotC is the best out of those 3 due to the sheild neglecting damage in trades and teamfights if you play Irelia in a tankteam fighting style . I take warlords for a better 1 v 1 , split push style . <| sep |> BS . They roost in the tops of trees . <| sep |> I just bought the top AF version for $ 19 . 95 including shipping from a US retailer . <| sep |> Seriously . We ' d be naive to think it wasn ' t already , it ' s just that now it ' s being publicly acknowledged .
