what do u mean by reload gem?About the skill...I currently have dual strike and cleave on my hotbar...but it just use cleave...
It's likely only using cleave because it's higher up in the Exile.cs routine so it never gets down to Dual Strike. I had the same issue until I changed cleave to only be used when 2 or more targets iirc.
You have to open up Exile.cs in notepad or Visual Studio or something like that and find and change the line
Register("Cleave"); to something like
Register("Cleave", ret => NumberOfMobsNear(BestTarget, 12, 2));
that would have it only use cleave if there are at least two targets within 12 range of your target and use double strike otherwise.
