You learn the minor illusion and shadow step cantrips. You are also imbued with the darkness, darkvision, pass without trace, shadow blade*, and silence spells, each of which you can cast once before you have to finish a quick rest, using Wisdom as the spellcasting ability for these spells.
While in an area of dim light or darkness, you are imbued with the invisibility spell, your movement speed is doubled, you can take the Hide action as one action, and you have resistance to cold and necrotic damage.
You can take the Magic action to cast the shadow of moil* spell.
Once you use this feature, you can't use it again until you finish a short rest, unless you expend 5 stamina points to use it again.
