Gnomish Fade

You have learned a magical trick for fading away when you suffer harm. You gain the following benefits:

• Increase your Dexterity score by 1, to a maximum of 20.
• Immediately after you take damage, you can use a reaction to magically become invisible until the end of your next turn or until you attack, deal damage, or force someone to make a saving throw. Once you use this ability, you can’t do so again until you finish a short or long rest.
• You have inherited the innate spellcasting ability of your ancestors. This ability allows you to cast nondetection on yourself at will, without needing a material component.

Intelligence is your spellcasting ability for these spells, and you cast them at their lowest possible levels.
