Alluring Ambush

I'm having trouble completing this challenge, running with all points in the strong box tree, using Winged Ambush Scarab and paying 4 chaos on kirac. However, my maps always come with an additional 14.
Does anyone else have this problem?

I did this easily with a kirac mission that is essentially giving you monstrous treasure.

Thank you for helping friends. I managed to close it with strongbox target memory
