beBufff is an simple addon that keeps you informed about your buffs.
There are 3 things that it can do for you:
Buff Gains / Fades:
There are 2 Arrays for Gain, and 2 for Fade, where one is for a Sound that is played on Event and the other is for a chat message.
Weapon Enchant Fade:
These are three simple variables. 2 to activate or deactivate sound and / or text message on fade, and the third is the sound file that is played.
