Could we please get the ability to have a sound alert attached to various types of diminishing returns expiring on ourselves/enemies? it would really help me and a lot of others have improved awareness im sure.

If possible It could be nice to have the option to have it alert us x seconds before it expires too to plan ahead. Thanks !

Diminish is now in maintenance mode so new features won't be implemented sorry, only bug fixes and new DRs.

You may configure visuals and finish effects for any cooldown frame using OmniCC addon with a group rule set to DiminishIcon, but I dont think it supports sound effects sadly. However, you can e.g change color & enlarge the cooldown text by a certain percentage when there's 5 second left on the DR timer and so on.
