Predecessor Builds > Sevarog > Perma Split Push Mega Scaling
Note: Anytime in the items section I refer to "opponent" or the person you are going "into" I mean the person most likely to match your split, not necessarily your opponent in lane. Exception being first items as you may get it before laning ends and the components help with laning.
This build is entirely for split pushing and essentially never grouping (with exceptions of course).
At 20 minutes you basically stat check everyone in the game unless they are fed and because of your sustain you can stay in side lane nearly indefinitely. At this point take as many resources as you can (enemy jg camps, waves, buffs, etc.). No one can 1v1 you and you have the best self peel in the game, so it is very hard to get punished.
This build is how I play Sev and get the most fun out of him. It definitely isn't optimal but it is for side laning and 1v1.
