Random spellcasting mechanic idea plus weirdo ability check idea.

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.
