It should be set so that finnigan steps onto a panic point and pushes erratic off followed by awol stepping onto the last panic point. Blinky and primal will be your damage dealers if you use attractor to pull erratic after he’s pushed off the panic point. It should line up so that primal double taps and blinky deals the final blow so that the lava can finish erratic off.
(If you decided to use the stim pad in center instead to boost primals lunge that would be a good idea.)
