Twilit/6th

Metamagic

At 6th level, you learn to more flexibly cast spells. You gain the Metamage feat, even if you don't met its prerequisite. If you already have this feat, you can instead gain any other feat for which you qualify.

Fading Step

Starting at 6th level, your mastery over otherworldly magic accents your movements through this world. Whenever you aren't concentrating on a spell, you hover just above the ground. While hovering, you still use your walking speed as normal, but you can choose to be unaffected by ground-based difficult terrain, friction-based hazards like slippery ice, and pressure-based traps.

Hovering doesn't prevent you from falling, but it does prevent you from taking damage and landing prone if you fall.
