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.
im yet to get a review first guide and not sure how does this work...., on few words...
ROA gets you tons of hp (because of passive), AP for poison (steady damage) and a 1:1 fling
Sunfire= armor + HP, more steady damage
Force of Nature + tons of HP = you won't die
last item, Rylais Scepter is situational, if everything goes wrong glue + slow from poison and get out of there (ghost+force of nature+ult = none will catch you)
even if someone those, you can fling them and they are slowed again :)
some little tips...
everything is about the way you move, how and when do you run toward enemies (sometime just to make them thing you want to fling them) and get some creeps through poison, etc
be creative for the 6th item
singed is a very fun champ to play try him once and you will love it
just note.... move runes +4.5%, masteries +3%, boots, force of nature +8%, ghost +40%, 2 ranged slows (exhaust, glue), mobility its the name of the game
Exhaust, +0.5s. multiple uses, stopping karthus ult, kats ult, the carry, slow etc... i love exhaust
