Somewhat silly idea for spellcasting.
- The player has no "actual spells from the book"
- They get as many spells as they are of level (10th level = 10 spells).
- They describe the spell and its effects.
- If the spell does damage its 1d4 per level of caster (2nd level wizard 2d4 damage)
- If the spell has a duration it is 1d4 per level in rounds of the caster (1st level is 1d4)
- If the spells cures it is 1d4 per level of caster. (3rd level 3d4)
- Any spells that cause damage or have an effect are subject to a saving throw. (attack rolls are not needed).
What I like about this idea, especially for new players, I can just say "alright what is it that you want to do?", and then have them describe the spell in detail. This might also give way to new spells. I think it might keep a player from randomly looking at their character sheet and wondering "do I have a spell that will help us here?".
Anyways, just an idea that I might put into practice.
Ability check idea!
Alright rather than a DC check or a roll under, I kinda like the idea of a target number for any check. The math is 17 - your level + modifier = target number. So a 3rd level character needs to roll over 14 with modifiers to be successful. Capped at 10 I think, so there's still a chance of failure. So at level seven you would always have to roll 10 or higher to be successful.
I actually wouldn't mind doing this same idea for saves and thieving skills. If any PC other than a thief attempts something, the math might be 19 everytime. 19 - your level + modifier = target number.
