Half-Elf Traits
Darkvision. Thanks to your elf blood, you have superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of gray.
Fey Ancestry. You have advantage on saving throws against being charmed, and magic can't put you to sleep.

Teleknesis Feat
Minor Telekinesis. You learn the Mage Hand spell. You can cast it without Verbal or Somatic components, you can make the spectral hand Invisible, and its range and the distance it can be away from you both increase by 30 feet when you cast it. The spell's spellcasting ability is the ability increased by this feat.
Telekinetic Shove. As a Bonus Action, you can telekinetically shove one creature you can see within 30 feet of yourself. When you do so, the target must succeed on a Strength saving throw (DC 8 plus the ability modifier of the score increased by this feat and your Proficiency Bonus) or be moved 5 feet toward or away from you.
