Is this "Faetouched" homebrew race balanced?

Question

I have here attempted to create a race that is to humans and half-humans like Eladrin is to elves. I am slightly worried that it is overpowered and if it is, please let me know how I can fix it.

Answer 1

Balanced and ready for playtesting

I'm going to use Detect Balance to assess how powerful this race is. This tool assigns scores to various racial features based on how useful they are. A good homebrew race should score between 24 and 27 and should never exceed 30. Here's how the calculation comes out for your race:

With a score of 27 your class is exactly where is should be in balance terms. Both your subraces have identical features so I have just assessed them together.

There is one issue with the Blessings of the Queen of Air and Darkness spells. Normally you would gain a cantrip at first level, a 1st level spell at third level and a 2nd level spell at fifth level. Snillocs Snowball Swarm is a 2nd level spell which, in theory, makes this slightly stronger than it should be. I say in theory because SSS is a slightly underwhelming spell for its level. Still it may be good to replace this with Ice Knife to bring it in line with other races with similar abilities without changing the thematics too much.

Additionally equated the Faerie Cunning trait to the Elf's Fey Ancestry. Yours is actually slightly better with the addition of the frightened condition and the Feywild part. Makes your races slightly stronger than detect balance would indicate but still within fair bounds.

I like the theme of this race and the abilities work well together. This is ready for playtesting, and I doubt you will encounter any issues.
