you will have to convert the mir3 wil to a mir2 wil
edit the will so that the mons are in the right order for the mir2 client to read them
add the wil to your mir2 client folder
find the appr and add the mobs to your mir2 DB
go ingame and spawn the mob
ps i have already done all of the above and will be realesed when my patches for my server are online
dont know when you will have to wait
BH
edit
they are also in the foundation patches and afew other server patches
