Things have slowed down a bit as I've transitioned from full-time to part-time work on Demon, but slowed down doesn't mean stopped:
In the month or so since the last post, not only have I finished the icon art for the 160+ new abilities coming in the next build...
...but, as of now, 140 or so of them are also implemented.
A reasonable question to ask would be why so many? It goes back to Demon's random modifier system: every 1/3 of the game uses a different set of random modifiers that can be applied to demons as they spawn. Each random modifier is also supposed to have level-appropriate abilities it chooses from to give to demons that receive it... thus, since the build is the first build with content from the last 1/3 of the main game, I needed to make the abilities to fill out the new set of modifiers' lists properly.
I also wanted to make SP-denial and physical/elemental hybrid builds more attractive and interesting, so some of the abilities were added to accommodate that as well.
This is one of the last big tasks left before the next release, though there are plenty of smaller ones and a fair bit of testing still to go, but I'll get through it.
Hoping for a March release at this point.
