Haha, I didn't even realize how the Conjuration spell fit the theme until you pointed it out — I mainly just added it because I enjoy summoning mechanics, and I like when missions give you opportunities to use special models specific to the scenario.
Fair point on the complexity part; that's definitely an easy trap for me to fall into when writing this kind of thing (I just have too many ideas, and sometimes find it difficult to accept that it might be better not to use all of them XD). I do think the amount of stuff here should be manageable, but as the mission's author I might obviously be biased in that regard — if anyone else is reading this, I'd appreciate some more opinions on this matter :D
