Twilit/10th
From Legends of Hyrule
Fused Power
Starting from 10th level, when you overpower a researcher spell, treat your Magic Limit as being 1 point higher than it otherwise is. This feature doesn't affect what spells you are able to learn, nor any other effect depending on your Magic Limit.
From 14th level onward, you can instead overpower the spell to 2 points higher than your Magic Limit.
