5e Musings: Aasimar Racial Traits

I've always felt bad for the Aasimar. When compared to their fiendish cousin the Tiefling, the Aasimars always seem to get the short end of the racial stick. I believe they were basically written out of 4th Edition (as far as I'm aware, anyway), and I don't believe they've made an appearance in 5th Edition yet.

With that in mind, I wanted to give these celestial planetouched some love. Using the Tiefling as a guideline, I've created racial traits for a 5th Edition version of the Aasimar. Although I'm still uncertain about certain elements of these traits, I thought I'd post it anyway and let others try it out (and possibly give me some feedback).

AASIMARS

Ability Score Increase: Your Wisdom score increases by 1, and your Charisma score increases by 2.

Age: Aasimars mature at the same rate as humans but live a few years longer.

Alignment: Aasimars might not have an innate tendency towards good, but many of them answer the call. Good or not, a righteous nature inclines many aasimars towards a lawful alignment.

Size: Aasimars are about the same size and build as humans. Your size is Medium.

Speed: Your base walking speed is 30 feet.

Darkvision: Thanks to your celestial heritage, you have superior vision in dark and dim conditions. You can see in dim light within 60 feet of your 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.

Heavenly Resistance: You have resistance to radiant damage.

Celestial Legacy: You know the thaumaturgy cantrip. Once you reach 3rd level, you can cast the heavenly rebuke* spell once per day as a 2nd level spell. Once you reach 5th level, you can also cast the daylight spell once per day. Charisma is your spellcasting ability for these spells.

Languages: You can speak, read, and write Common and Celestial.

*Heavenly Rebuke is simply a reskinned Hellish Rebuke, dealing radiant damage instead of fire damage.
