Heyy guys... Fellow DM here. I'm making a new Core Engine and leveling and Class System for my DnD campaign called The Playwright Campaign. The main differences is that now magic is based off mana use. And when you level up there is a level tree that you spend points on to increase your classes stats. The magic also each has their own unique skill tree you spend points in to unlock more magic spells. I developed each class skill tree as to fill a certain niche in the party. So that everyone feels most important. I have included a screenshot of the Core Rules and one of the Rogue Skill Tree. Please tell me what you guys think! I really need to make sure this is balanced well.
