Weave Sight Replaces Darkvision As an action you can activate Weave Sight for 1 minute, while this is active you can see any manipulation of the weave in any space you could see with your normal eyes, however you also leave yourself vulnerable to magic when exposing yourself to the weave, meaning you have disadvantage on every saving throw caused by spells. Once you use this ability you cannot use it until your next long rest. You can cancel this ability with another action at any time during the duration.
Arcane Affinity Replaces Keen Senses You have proficiency in the Arcana skill.
Mana Trance Replaces Trance Unlike other elves, Mana Elves have to sleep like normal people due to them having stronger ties to magic than to the divinity of the elven gods. However while taking a short rest you can instead enter a trance infusing yourself with the weave, at the end of that short rest you can restore 1 spell slot of your lowest level. This cannot restore more spell slots than is your maximum for that slot, when you reach that maximum this ability no longer works. This also cannot be used at the same time as other abilities that restore spell slots on a short rest.
