Aspect of Baal (Demolith)

Spider Climb. The aspect can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.

Legendary Resistance (1/Day). If the aspect fails a saving throw, it can choose to succeed instead.

Demolith Subtype. The aspect has the "(demolith)" tag, which has no rules of its own, but is a tag that affects the aspect in the same way that it would affect a demon or devil.

Semi-Immortal Nature. The aspect can't die of old age unless affected by magic of a spell of 6th level or higher and doesn't require food, drink, air, or sleep.

Web Walker. The aspect ignores movement restrictions caused by webbing.

Heated Fire. Fire damage dealt by the aspect bypasses fire resistance. Additionally, whenever the aspect deals fire damage to a target that is immune to fire damage, the target does not take no damage and the amount of fire damage dealt by the aspect is reduced to 2.

Movement Immunity. The aspect automatically succeeds on saving throws against being forcefully moved against its will.

Multiattack. The aspect may use its Destructive Presence and then makes two attacks.

Claws. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 9 (1d8 + 5) slashing damage and the target must make a DC 15 Constitution saving throw, taking 10 (3d6) cold, necrotic, force, or fire damage on a failed save, or half as much on a success.

Eldritch Wave. Ranged Spell Attack: +10 to hit, range 80 ft., one target. Hit: 14 (2d8 + 5) force damage.

Leg. Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 12 (2d6 + 5) slashing damage.

Destructive Presence. The aspect lets outs a cry as it channels its destructive fury into itself and out of others around it. Each creature within 120 feet of the aspect must succeed on a DC 16 Charisma saving throw or have a -1 bonus to hit and to damage and have the aspect have a +1 bonus to hit and to damage for 1 minute. These penalties stop stacking at -4, and the bonuses stop stacking at +4.

Festering Minions (Recharge 5-6). The aspect summons 2d4+1 festering appendage demoliths, 2d8 destruction spawn demoliths, or 2d6 trooper demoliths with no chance of failure that appear at points the aspect can see within 60 feet of it. A summoned demolith acts as an ally of the aspect, and can't summon other fiends. It remains for 5 minutes, until it or the aspect dies, or until the aspect dismisses it as an action.

Incineration Star (Recharge 6). The aspect raises its hands in the air before causing blazing lanes of hellish flame to extend out from it in the form of four 50-foot long, 5-foot wide lines across the ground. Each target within the area of a line must make a DC 17 Dexterity saving throw, taking 39 (6d12) fire damage on a failed save, or half as much on a success.

Spellcasting. The aspect casts one of the following spells, using Charisma as its spellcasting ability (spell save DC 17, +9 to hit with spell attacks) not requiring material components:

At Will: detect magic, ray of frost (2d8, reduces speed by 20 ft.), dimension door, fireball, magic mouth

1/day: project image, fiendish brand (cold, necrotic, force, aetherion, or fire damage)

The aspect 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. The aspect regains spent legendary actions at the start of its turn.

Charge. The aspect moves up to half his speed.

Spellcasting Strike. The aspect casts one of its "at-will" spells or makes a melee attack with disadvantage.

Hellfury Shockwave (Costs 3 Actions). The aspect releases a powerful shockwave in a 60-foot radius. Each target in the area of the shockwave must make a DC 19 Dexterity saving throw, taking 10 (3d6) wrath damage, be knocked prone, and be stunned until the end of the round on a failed save, or half as much damage and only be knocked prone on a success.
