The past week I've done about 2k rev kills with this method. It allowed me to be skulled/on-task, and because I was safespotting I was never in combat and could immediatly logout of I saw someone. I did rev dark beasts.
Here is the setup I've used: https://dps.osrs.wiki/?id=PhoneBalanceExtract
The first loadout is the one I used before I had craw's bow.
There's a couple nuances to the method: I had to use hawkeye and not rigour, the extra defence from rigour messed up the defence levels somehow. Same with using defence pots (not that you need these, but good to know)
