OP Hecarim build
9-21-0 (0-21-9 is optimal, but I was testing lolthornmail hecarim with a friend)
Flat armor reds and blues and scaling armor yellows and quints
Thornmail, Ninja Tabi, Randuins, GA, Frozen heart, and Funfire cape.
Hit the speedshrine and when you are about to hit the laz0r part, press E. Once you get to the top, hit R to avoid getting hit by both lazers simultaneously. Most of the way down, you will proc the GA. When you come back up, stroll out of the base like a boss with ~300 HP.
What other champions can solo the enemy fountain and live to tell the tale?
