So apparently Sweeping Strikes is bugged or it works as intended which is quite bad tbh. Idk if this was addressed before, but when using a Mortal strike on a target below 20% it doesn't cleave the second target, and only Execute works (as shown in the video). It's also vice versa. If u use a Mortal strike on the target above 20% and the second target is below 20% sweeping strikes doesn't work.
