There haven't been any updates on this recently but that's because everything I've been working on recently would fall into spoiler territory. Unfortunately as it's an RPG the story is one of the main components, so there's not a whole lot I can show. I can say that making this type of game requires lots of math to make sure that things are balanced though. There's a lot of algorithms and etc working in the background and it can be tempting to just set a damage value to "stat * x" and call it a day, but if you don't try running some numbers through it you won't know how over/underpowered it will be. I've run into that a few times already where I just went "fuck it" and set the numbers to something that I thought sounded about right but in practice they were way higher than they should've been.

And when I say way higher than they should've been, I mean that certain skills were doing around 600x normal damage, or a boss ability would inflict 4 billion points of damage to EVERY party member.

Avoiding this is as easy as taking the stats the enemy/character will (or might) have and working through the formula. If the result is way too high, lower the numbers in the formula or rewrite it. If it's way too low, increase the numbers or rewrite it. Alternatively you can just create a test enemy to use the skill so that you can see how it works in actual gameplay. If you go this route I'd also recommend increasing/removing the damage cap temporarily so that you can see the full damage value to ensure it isn't too high.

Ultimately damage values for skills are an incredibly delicate balancing act. You want to make sure that every skill still has some kind of purpose even into the late game, but making all the skills do the same amount of damage will make them all feel the same and unsatisfying.
