Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
to who that build is good?
that build is good jest to does that know how to play irelia and they geting feed if you start with irelia dont use that
you buy all the thing that i say until you dont have place then you will replace the dorans blade with buildthirster and then sell the shoes and buy phantom
but id the team against you have champion with alot hp (like mundo/vlad) youshoud replace the 1 of the phantopm/buildthirster and buy a mardredsbloodrazor
again as i said only pro irelia that know what they doing and getting fed can buy this items becusee the very expensive
