Aspabo, the Weave of Abjuration

Abjuration Mastery. When Ἀσπίς casts an abjuration spell that requires him to make an ability check as a part of casting that spell (such as counterspell and dispel magic), he can add a +7 to that ability check.

Arcane Ward. Whenever Ἀσπίς cast an abjuration spell of 1st level or higher, Ἀσπίς can simultaneously use a strand of the spell's magic to create a magical ward on himself that lasts for 24 hours. The ward has a hit point maximum of 50. Whenever Ἀσπίς takes damage, the ward takes the damage instead. If this damage reduces the ward to 0 hit points, Ἀσπίς takes any remaining damage.

While the ward has 0 hit points, it can't absorb damage, but its magic remains. Whenever Ἀσπίς casts an abjuration spell of 1st level or higher, the ward regains a number of hit points equal to twice the level of the spell.

Innate Spellcasting. Ἀσπίς’s spell casting ability is Intelligence, (spell save DC 24, +16 to hit with attack spells). Ἀσπίς can innately cast the following spells, requiring no components.

At-will: All cantrips, abjuration spells of 6th level or lower, detect magic, witch bolt, silence, lightning bolt, slow, greater invisibility,        

5/day each: abjuration spells of 7th level or lower, animate dead, bestow curse, clairvoyance, dispel magic, hold person

Limited Magic Immunity. Unless Ἀσπίς wishes to be affected, he is immune to spells of 4th level or lower, and has advantage on saving throws against spells and other magical effects.

Magic Weapons. Ἀσπίς’s weapon attacks are considered magical weapons for overcoming resistances.

Rejuvenation. If Ἀσπίς is reduced to 0 hit points his body explodes into magical power and crumbles to a pile of dust. Unless a wish is cast on the remains within 24 hours, Ἀσπίς raises, at full strength, within 5 feet of his remains.

Weave Rot. A creature that touches Ἀσπίς or hits him with a melee attack while within 10 feet of it must make a DC 24 Constitution saving throw, taking 24 (7d6) necrotic damage (which is included in it's attacks), its movement reduced by half, and it has disadvantage on all attack rolls and ability checks on a failure, or half as much damage on a success. The target must make an additional saving throw at the end of each of its turns. On the first failed save the targets AC is reduced by 5. On the second failed save, whenever the target casts a spell, they must first make a Constitution saving throw of 10 + the spells level or the casting is wasted. On the third failed save the the target is also reduced to 0 hit points and dies after 1 round and its body turns to dust. If the target succeeds on saving throw it removes the most recent condition. The target must continue making saving throws until all conditions are removed.

Multiattack. Ἀσπίς uses his dreadful glare and makes two slam attacks.

Slam. Melee Weapon Attack: +15 to hit, reach 10 ft., one target. Hit: 28 (4d8 + 10) bludgeoning damage plus 24 (7d6) force damage and the target must make a DC 24 Constitution saving throw or be inflicted with weave rot.

Despairing Glare. Ἀσπίς targets one creature he can see within 120 feet of him, that can also see him. The target must make a DC 23 Wisdom saving throw or become frightened for 1 minute. If the target fails the saving throw by 5 or more, it is also paralyzed for the same duration. A target can attempt another saving throw at the end of each of its turns. If a target succeeds on a saving throw, or the effect ends for it, it is immune to Ἀσπίς’s despairing glare for the next 4 hours.

Ruin (Recharge 5-6).  Ἀσπίς selects one target he can see within 480 feet of him. The target must make a DC 23 Constitution saving throw, taking 52 (15d6) necrotic and 52 (15d6) force damage on a failed save, or half as much damage on a successful one.
