Manawyrms are grossly overpowered. Nobody should be able to summon something that powerful so early and cheaply. Maybe at 30 death gems, Conj 7. Alternately, you could change it to something like Feast of Crows, but for Earth gems? Can you do that?

Spiders are cool but probably underpowered/too expensive for where they are. Maybe make them the research 1 2+ for 2 gems.

The tank does not have any graphics and crashes the game when it is created.

Killermole also crashes the game when you try to look at the battle, and apparently does not do anything.

Ancient Moss has a hatchet attack.

Raise Cilosyb is an in-combat spell that does not appear to do anything.
