Sorcerer/14th
From Legends of Hyrule
Overcharge
Starting from 14th level, when you cast a powered sorcerer spell that deals damage, you can deal maximum damage with that spell. You suffer no ill effects if you do so with a spell of 4-points or fewer (2nd level or lower).
If you use this feature with a spell of 5-points or more (3rd level or higher), you take 1d10 psychic damage for each magic point of the spell, immediately after you cast it. This damage ignores resistance, reduction, and immunity.
