daemon_n, It will be more complicated than you think because if I add all the creatures of level 7 and 8, (downgrade and upgrade) in the same dwelling I think that the ERM will collapse wherever you see, no matter well written it is because has no logic, so I think I will only focus on level 8 dwellings and their respective upgrade to make the script for "Resistance I" work. Remember there is a second upgrade for level 8 creatures.
