Viper would of been better if it had a different name

[SeverianLyonesse]

If it is meant as a 9 reference they picked a really obscure way to to it
(Help text for Rune Tooth if anyone wants to know, also Zidane's weapon with poison added effect)

Hell, RUNE TOOTH would have been a better name. It better communicates Zidane and Hunter/Ranger, as well as suggests a runeblade/mystic knight. While also having a more solid "bestial" motif than a simple snake.
