Will there be a pumpkin monster?
At the same time, a unit is "interesting" to the extent that it fits into my fictional lore. For example, someone might think that a golem, a cannon, or a robo-demon would be suitable, but I, on the contrary, believe that engineering among dwarves should not be very developed; magic has taken its place, so there will be no such units. These dwarves' guns run on magic, and instead of golems, dwarves make ifrits.
I'm currently working on a ranged unit – it's a demon sealed in a stone.
