Newly Updated For Event Sounds in DBM!
Now that DBM has added a new feature Event Sounds in options
You now can can add Arnold in for Victory, Defeat,
Set Sound Played for pull timer start
and
Set sound played for encounter engage
Also Music Tracks!
After Downloading click DBM on the mini map, go to options, Then Event Sounds. There you can pick what sound you want. Arnold is mixed in with the other DBM sounds so you'll have to go though the list to find the right ones you want but it should be easy to find.
You can have a look on the photo description I posted with is add-on also.
