I need suggestions ... Ulm against Mictlan...

[Norfleet]

Alas, gateway is only available at Thaum-5....a high mark for Ulm, given the poor research conditions...and complete lack of astral mages.

Also, it totally fails to solve your problem, as Gateway can only allow you to travel between friendly labs. You'll have to do your raiding on foot. Laying waste to the Mictlan blood economy is definitely a bonus, though....and odds are that Mictlan will have very little he can STOP you with, as his national troops are crap and his fiends are limited in number.
