I was hoping the community could help me with 2 questions I have about a magic ring I created recently for my Homebrew campaign.

1. See the item stat block below. The problem is that I cannot find a way to have DnD Beyond pick up the Fey Ancestry traits (advantage on savings throws against being charmed, sleep immunity). The system already displays this on the character sheet for Elf characters and many monsters, so it must be coded already. When I edit the modifiers to the item, there is no Sleep condition to be immune to, and there is no Advantage against Charmed. Any thoughts on how I can get this to display properly like on my Elf characters where it shows up in the Saving Throws block?

2. I'd love any feedback on the ring and any comments or suggestions to make it better.

Thanks all!

Ring of the Alder Fey
Ring, very rare (requires attunement by a Druid, Elf, or Gnome)

This magical ring is made of intertwining alder twigs and leaves. It emits a soft, hazy purple-orange glow reminiscent of the Feywild, where it was crafted by Eladrin wyldfae.

While wearing this ring, you have resistance to poison, advantage on saving throws against being charmed, and magic can’t put you to sleep.

You gain a +1 bonus to AC and Wisdom saving throws while wearing this ring.

Notes: Bonus: Armor Class, Bonus: Wisdom Saving Throws, Resistance: Poison, Druid, Elf, or Gnome, Warding, Jewelry

There is not an already coded shortcut. To do Fey Ancestry:

Modifiers -> Advantage -> Saving Throws; with the Details field as "against being charmed, and magic can’t put you to sleep"
