Aelwyd Trutanniel

Legendary Resistance (3/day). If Aelwyd fails a saving throw, she can choose to succeed instead.

Spellcasting. Aelwyd is a 20th-level spellcaster. Her spellcasting ability is Intelligence (spell save DC 22, +14 to hit with spell attacks). Aelwyd has the following wizard spells prepared:

Cantrips (at will): booming blade, mage hand, message, prestidigitation, sword burst

2nd level (3 slots): detect thoughts, mirror image, misty step, suggestion

Moonblade. Melee Weapon Attack: +13 to hit, reach 5 ft., one target. Hit: 14 (1d8 + 12) slashing damage.

Bladesong. 6 times per long rest, Aelwyd can use a bonus action to start a Bladesong, which lasts for 1 minute and grants her the following benefits:

Aelwyd gains a +5 bonus to her AC, her walking speed increases by 10ft., she has advantage on acrobatics checks, and she gains a +5 bonus to any CON saving throw she makes to maintain her concentration on a spell. It ends early if she is incapacitated, if she dons medium or heavy armor or a shield, or if she uses two hands to make an attack with a weapon. She can also dismiss the Bladesong at any time she chooses (no action required).

Aelwyd adds +5 to the damage of her melee weapon attacks while her Bladesong is active.

Song of Defense. When Aelwyd takes damage while her Bladesong is active, she can use her reaction to expend one spell slot and reduce that damage to her by an amount equal to five times the spell slot's level.

Shield. An invisible barrier of magical force appears, providing a +5 bonus to Aelwyd's armor class and negating any damage from magic missile.

Aelwyd can take 3 legendary actions, choosing from the options below. Only one legendary action can be used at a time and only at the end of another creature's turn. Aelwyd regains spent legendary actions at the start of her turn.

Attack. Aelwyd makes one attack with her Moonblade.

Cast Spell. Aelwyd uses a spell slot to cast a 1st, 2nd, or 3rd level spell that she has prepared. Doing so costs 1 legendary action per level of the spell.

Move. Aelwyd moves up to her speed without provoking opportunity attacks.
