Hello,
This works for me, just sometimes when the npc reaches it's "refuge" point, it's hard to kill cause of the radius.
Anyways, with a fe goli with 10 shields and 5 speed gens on ship. 4 drones with shields rest lasers. That's the ship config.
Radius for boss- big kriss, small kriss is 800.. 750 for big kriss and 700 for regular lil kriss
