That sounds solid; I have an idea for a No Moon necromancer who was enlightened to the bleak arts by a terrible experience brought on by a Deathlord's actions, and who is dead-set on avenging herself upon said Deathlord. Walker works great for that.
The only thing I have to ask is what you mean about combat. When it comes to Discord text chat, that's about as "together" as you can get without a live session kinda thing. It's at least a bit faster than forum posting, typically.
