The concept of the viper goes as far back as 2008. It resembled a snake/scorpion in this form. Concepts were done by Samwise Didier. Its current aesthetic is a cross between a cobra/scorpion and a wasp.
- Ocular Parasite: The viper grants detection to an allied non-massive unit. The viper can target other vipers or itself with this ability. It can only be used once. This ability has probably been removed as of April 2012, since the overseer has been returned, and the viper made into a "pure" spellcaster.
