all singed builds that where out there was difficult for me to play. i played and i ended up feeding over and over, because first i was not doing enough damage and i wasn't tanky at all. so i made this build. it is still very squishy early but boy it snowballs. the keystone just does a lot of damage when you have the poison on. if you could stick yourself to target keystone hits over and over and kills. if you have any question about any item or rune ask. I will also welcome your inputs. I am not a very high rank player, i am a singed lover with mastery 6 in singed. I just love playing this champion very high skill champion in my opinion. so i had a bad time since new runs couldn't let me push hard or proxy. Although with new system i don't recommend proxy early game, with these runes it is possible. but please be careful if you proxy, put vision on and don't feed.
