Since 1.5 is out it and you can make /effect commands, this plugin my be useless. However, I will continue to update this plugin for those who still want a plugin that does this that is permissions based.
This plugin allows you to type a command and be effected by potions. Each effect last 20 seconds.
/potion ? List of potions.
/potion [effect] ? Gives the effects of a potion.
/potion remove ? Removes all effects.
cmdpotion.use ? Allows the use of the plugin.
v0.4 ? Bug fixes. Updated to 1.7.2
v0.3 ? Added permissions support.
v0.2 ? Added /potion help and /potion remove, removed wither effect.
v0.1 ? Initial release.
