Viper

Viper the Netherdrake is a ranged agility Hero who can function as an excellent ganker and carry due to his slowing auto-attacks and his low cooldown ultimate. Although ganking is often made easier with Viper's presence, his true carry potential is revealed with sheer item power. Farming with Viper is relatively easy; while he has no area of effect abilities to clear waves, Nethertoxin makes last-hitting a cinch. However, active participation in ganking is very important before his ganking power wears out in mid-late game, due to enemy heroes playing more cautiously and obtaining better items. Poison Attack makes Viper very potent in hero harassing.
