It's definitely not a DnD clone. It's a class-less system where characters level up using a skill tree. It's very intuitive and allows for probably hundreds if not thousands of combinations (or at least it will once the skill tree is fully fleshed out).

That said it is still very much in it's infancy. Changes are being made almost daily. I couldn't tell you when it will be officially release but it feels like it will still be some time yet before all the kinks are worked out and it's a fully fleshed out system.

I haven't have access (hell I don't even have Foundry currently) but I'm liking the systems I've seen so far from some of the videos. Definitely tossed the idea to some of my players to gauge their interest.
