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.
this is the way i play renek, i play him very defensive and at the sametime deals alot of damage. He is very useful to play along a caster or just by himself, i have played renekton with this build and almost never fail.
Renekton is one of the best selflaners in the game, and with this build you should be succsesful!
