Probably the most potent skill in the game, since after been cast on one enemy, will infect close enemies afterwards.
Like a virus, it will only stop when the enemy cluster dies off before another enemy gets close enough.
Old programmer saying:
Iteration is silver, recursion is gold.
Also, just testing youtubes resolution/framerate settings (due to my previous upload got recoded quite downgraded). This clip was recorded using 960x540/30fps. then modified to 1920x1080/60fps. Lets see how youtube encoding ends up for this one.
