If you want to get really fancy you can use the -10 (no mana) to +10 (Very high Mana) of continuous mana with normal (0) on 10 (this is where the cumulative percentage is 50.0%) with each number ±2.

Yes this makes 15-18 No mana but the cumulative percentage of getting 15 or higher is 4.5% (100.0-95.4) which is effectively a 1 on a d20 (auto failure under 1 and 20 rule)
