Ok, it takes a little over 30 minutes to charge two tears in a bot game. Maybe less.
1/8/21 masteries? Strength of Spirit is very strong.
It's actually hard to make gold faster than you can charge tears. At first I thought Catalyst after Tear would be good. Maybe it's better to get a Catalyst after Tear in a more serious game, because recalling repeatedly early-to-mid game is only acceptable in bots.
AAS before Manamune, I think? AP is just better... Singed only has autos and fling for Muramana procs. Then again, Manamune is cheaper, letting you start on tear #2 that much sooner.
After your two tears and RoA, then what? GA because Singed is a jerk like that? Deathcap for the lulz? Malady for Muramana good times?
I'm open to both fun and serious builds here. I don't really play Singed seriously, but the new Tear is neat.
