Do you have, um, plans to make succubi have those powers as invaders?
Because that will just be scary as all get out.
The forces of good have no matching power. Elves don't have magic yet. All the magic centered races seem to be on the dark side so far.
Dwarves have some magic, sure, but I've never seen one as an invader and it doesn't seem to be a big part of their race. I've never even built the school of wizardry when I play dwarves. What's a mage able to do that a masterwork steel axe can't?
I toyed around with the succubi a little so far, and their temples are insanely powerful. Insanely so. They're missing a lot of stuff still, it seems, but what they've got is so very powerful.
I don't know how they actually play yet though in terms of balance. The reagents for their temples and such I spawned with dfhack so it might be much more difficult to get them in real game play.
