An eye on Viper is an addon that keeps track of how much mana you have and the viper is still on in that case it warns you
if you have any other version installed then 1.01 or newer you need to remove the old once "A_eye_on_viper" folder

commands

/eov = show all commands and current mana setting
/eov 75 = set the alarm to go off if you haver more then 75% mana and viper still on (can be 2 to 100)
/eov sound = this turn the sound on and off
/eov power = this turn most of the addon on and off
/eov text = this turn the warning text on and off
/eov version = this turn the search for newer versions on and offa

if you dont like the sound then the alarm gos off you can go in to the addon folder and repace the WarningSound.wav file with anyting you want but its need to be in .wav format
