Alirak (archmage)

Acquired Legacy. After studying elves for a century, Alirak has learned how to replicate their nature on himself: magic can't put Alirak to sleep. Alirak does not sleep at all, instead he meditates deeply, remaining semi-conscious for 4 hours a day.

Diabolic Essence. Alirak counts as a fiend for the purpose of targeting spells. As such, a spell which usually affects humanoids like hold person has no effect on him.

Devil's Sight. Magical darkness doesn't impede Alirak's darkvision.

Magic Resistance. Alirak has advantage on saving throws against spells and other magical effects.

Legendary Resistance (3/Day). If Alirak fails a saving throw, he can choose to succeed instead.

Magic Absorption. When Alirak successfully counters an hostile spell with counterspell or dispel magic, he gains temporary hit points equal ten times the spell level.

Greater Concentration. Alirak can concentrate on two spells at the same time.

Greater Ring of Spell Storing. This ring can store up to 8 levels worth of spells at a time. Alirak keeps here important spells he may need but that he usually does not prepare daily, or some emergency spell like teleport or counterspell.

Bonus Spell. Alirak casts a cantrip or one of his at-will spells.

Elemental Adaptation. Alirak can become immune to one type of damage in which he has resistance, but he gets vulnerability to another type of damage among the ones in which he usually has resistance. He can choose where to put the bonus and the malus, but he cannot have more than two invulnerabilities at the same time with this privilege. A 3rd level dispel magic can end one of these effects and prevents Alirak from using this privilege for one minute.

Shield. Alirak casts shield on himself if someone beats his base armor class.

Counterspell. Alirak casts counterspell with the lower possible spell slot.

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

Cantrip. Alirak casts a cantrip.

Superior Misty Step (Costs 2 Actions). Alirak teleports himself 60ft to one point he can see.

Cast a spell (Costs 2 Actions). Alirak casts a spell of 3rd level or lower.
