Hasty

You have learned to channel your magic into raw, physical momentum, granting you the following benefits:

Ability Score Increase. Increase your Dexterity score by 1, to a maximum of 20

Speedster. You learn the haste spell. You can cast it once without expending a spell slot, and you regain the ability to do so when you finish a long rest. You can also cast this spell using any spell slots you have of the appropriate level.

Momentum. When you are under the effects of haste, you do not suffer the wave of lethargy if the spell ends because its voluntarily ended or because it reaches its full duration. You still suffer the lethargy if concentration is broken by damage or another effect.
