This build is a straight up classic that i haven't seen anyone play in a while... it used to be unbeatable, and probably still is.
REALLY ANY RANGED HERO WORKS. I prefer Storm Panda or Space Orc, because they are OP as shit (lets be honest)
Shockwave/FF/Flame
Vortex/Divine
Slow Poison/Darkness
HP Bonus/Abolish

Main lvl shock wave all game, unless they have some kind of spell that is countered by vortex then lvl shockwave to 6 and then rely on Auto attack to farm well. Never lvl vortex past 50 percent. Keep it at 50 so you can use it tiwce to wipe all their mana and still have extra lvls to put into slow poison.
The realy Str of this build is it can't really be countered... Honestly the only way to beat it is to out farm it, which of course is always possible, depending on the skill of the player. Once you learn to farm with SW this build is a general powerhouse.
