Fahdiz,
mainly I will try to post once for each turn, maybe I will consolidate some turns later on if there should be a lull in the game, but mainly I want to give a step by step account of what I am doing and why I am doing it.
This way I have the best possibilities to get some detailed feedback about what I am doing.
Concerning the Illithids,
I will switch between both actually. I will try to keep the unarmored ones (which I mainly plan on using) out of fights with fliers and recruit the armored ones when I got excess ressources.
The point about the unarmored ones having potentially a better mind-bLast is very interesting, too and might push me even further towards them.
Mainly I plan to use the armored ones at first while I research the magic I need to protect the unarmored ones later on.
IMO the better strategic movement will get more important in the later stages of the game than it is at the beginning.
Gibson,
I think I read in some threads that there seems to be no correlation between luck-scales and summons - just pure luck

- but having luck-3 surely can't hurt summoning
I randomized using the randomize function in Excel configured for the maximum number of wanted results. But throwing dice should work nicely, too. AFAIK there is no means to randomly choose a certain number of opponents in the game itself.
Thank you for the feedback
