Warring be aware that you need to have Mayura in you`re party to be able to recute Lamina, If you haven`t recute her yet save this until you have done so. This mission is fully possible to start and get without Mayura in you`re party and that make Lamina unrecuteable.
On the other hand if Mayura is recuted she will be preselected by the game upon starting this mission.
You Have complete the mission "Supply Line in the Desert" to get this mission.

First off you need to both have Mayura at mission start and make sure she is still alive after you have taken out every enemy she must not retreat. Keep her safe and out of harms way.
To be able to recute Lamia you need to have Mayura attack her once to trigger a convention. Lamia will retreat after this now you only need to keep Mayura alive until you have completed the mission. This mission is a bit tricky in the beginning make sure you are not overwhelmed by the large amount of enemy coming at you form the get go.01
