Scion said:I simply hate the 'refresh per level' abilities.
To me it would be just as bad to give a caster type X spell levels of spells and they will only get more with level up or a fighter type only Y hp before next level, better hope you get it in time!
Scion hates 'em, but I find the notion of limiting spells by level kind of intriguing. There should only be 13 moderate encounters (using 20-25% resources) between encounters anyway. Let the wizard recharge 5 times per level, and you should be gold.
