hi i just hit the level cap of 99 (don't know if you set the cap or if it's the engine) and noticed a problem i no longer have a stable income of skill points from my counting i need 294 to max out every characters skill tree and while maybe it could be said that we should not be able to max all of them even if i only wanted to max 4 character lets say the 4 first in order in the skill tree list Ryen, Tsubaki, Trey and Mira all off them would cost 110 skill points i think this is an problem. as you only get 99 points from leveling and then you have to find or grind for skill point and they are quite expensive in my opinion.

It's intended that the skill points are limited, and that skillstones are rare. You'll get more skill stones in the future content of the game, that's why they might feel a bit fewer than necessary.
Keep in mind that skills can be reset at all times, and setups for characters can be saved and loaded. This way, you can quickly change what character is fully buffed.
