When you enter melee combat without a weapon buff, such as Rockbiter, Windfury, etc, a bell sounds and a chat message is sent as a reminder to buff your weapon. This warning also occurs while in combat if the buff fades.

When Lightning Shield fades a chime sounds along with a chat message.

Sounds can be turned off/on. Type /said for the command menu.

This applies to Shaman only, other classes are not affected.
