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.
as you notice this build's name is CATALYST THE PROTECTOR which is an necessary item for singed and singed is kinda all about it he goes realy healthy with it early game .
i recomend lich bane instead of archangle or zhonya but if u were doin bad just forget about it and go for more hp and more sunfire but if u were doin good just get it early game .you will notice u dont have health problem ITS because you have 3 catalyst the protector which protects singed .
i dont really like Guardian angel anymore because its nerfed but its grat for armor and magic resist u can get it instead of one of sinfires .
singed is a really cool champion he is easy to build as long as ur ap tank he is fast ,a tower diver ,poison ,A POWERFUL slow .
but he is not overpowerd and hes not underpowered .
singed is one of the champions that can destroy the enemy team .always use ur slow even when its not necessary because its really annoying :D
and make sure u have cleanse spell.
i think cleanse ans ghost are must on singed .
umm have fun and have a drink ;)
