Based on <a href="https://roll20.net/compendium/dnd5e/Rules:Spellcasting%20Tables" rel="nofollow">https://roll20.net/compendium/dnd5e/Rules:Spellcasting%20Tables</a> and classes like the ranger, a half caster should have 2 first level spell slots at level 1 When setting up a custom class in the builder with half spell slot progression, the character doesn't get spell slots until level 2 (Like with the 2014) rules Can be worked around by setting up manual spell slots, but is confusing since the builder seems to be based on the 2024 rules
