Yeah, obviously there is a bit of room to tweak several of the specifics to your own personal preferences. You could swap in death-3 and up to magic-1, though that may make R'lyeh more challenging and hit your long term income. Pick your poison.

@Fantomen: No doubt at all that there's some very nice stuff in enchantment, but I don't think I'd hit it before construction unless there was something specific I needed for my situation. Construction gives you skull mentors and lightless lanterns, which then makes the enchantment research a snap. It also gives you skull staffs, and hence darkness & drain life which is a critical target. There's also loads of secondary big benefits available from wave breakers to earth boots and water bracelets.
