If you can jump down and in between and below (not too much) there is a safe spot from turrets. Get the xab on the other side of you have you can do what you want there. When he tries to run he hit the back wall and he will stop running. If he tries running down the he will just get caught on you and the turret so you should be all good. Make sure that you either have the other mobs with the xab or they aren't lured or stuck.
As for the other way. If you just hit the turret next to you it may lure the xab. If it doesn't run down to about the square in the middle and jump back. He may be able to see you from that distance. If he doesn't get lure do it again and just get lower and lower until he follows
