Aniela The Heavenly conflux

Divine liar. Aniela is a perfect liar unaffected by magic that would force the truth. nor can it be detected that she is lying. additionally if magic is cast on her that would reveal her nature it instead reads as whatever she wishes. 

True Conflux. When Aniela the heavenly conflux drops to zero hit points she is cocooned by the six elements. she regains 150 hit points, and immediately channels every element available to her. if she uses an impulse that ends channeling she instead loses the ability to use the impulses for that plane until she channels is again, losing none of the aura effects for that plane. She has access to her mythic impulses. this ability can only activate once, and becomes available again after Aniela finishes a long rest.

Rift. While not in conflict Aniela can make a  rift to any point in the multiverse except the heavens, and step through traveling there instantly. 

Divine awareness. Aniela knows if she hears a lie.

Magic resistance. Aniela has advantage on saves against spells and other magic effects.

Legendary resistance. 3 times per long rest when Aniela fails a saving throw she may choose to succeed instead.

Multiattack. Aniela makes 3 elemental bursts. these attacks can be from any element she has channeled, alternatively she can use her impulses as described in the impulses themselves. Charisma is her ability modifier for this; +14 to hit, Dc 22 for saves.

elemental Burst. Melee or ranged spell attack: + 14 to hit, reach 5ft. or range 120ft., one target. Hit: 28 (4d10 + 8) damage of her choice depending on what plane she has channeled. Fire plane (fire), water plane (bludgeoning or cold), air plane (slashing or lightning), earth plane (bludgeoning or necrotic), plant plane (piercing or acid), and metal plane (slashing or piercing).

Impulses. All impulses used by Aniela have the effect given by a critical hit of her elemental burst depending on the plane she has channeled.

Elemental serpent. Aniela forms an Elemental serpent  that she sends across the battlefield. she casts one of the following spells depending on which plane she has channeled; wall of fire (fire), Wind wall (air),Wall of stone (earth), Wall of thorns (plant/metal), Wall of water (water)  as her action. if she becomes unchanneled she automatically loses concentration on this spell.

Gerda Bloom (fire, earth, or plant channeled). Aniela grows a bud of elemental energy to a point she can see, the bud then blooms into a beautiful explosion leaving behind only the burnt shadow of a flower. She cast fireball as her action, this impulse ends her channeling. The damage of this fireball depends on the plane she has channeled; Fire plane = fire, earth plane = necrotic, plant plane = acid.

Megarad cutter. (air, water, or metal channeled). Aniela presses her hands together and shoots forth a compressed beam of elemental power. She casts lightning bolt as her action, this impulse ends her channeling. The damage of the bolt depends on the plane she has channeled; air plane = lightning, water = bludgeoning, metal = piercing.

Plane step. Aniela forms sandals of elements on her feet. She cast ashardalons stride as an action. the trail she leaves doesn't dissipate until she is no longer channeling even if she loses concentration on the spell. The damage is 3d6 of a type depending on the plane she is channeling; fire (fire plane), cold (water plane), lightning (air plane), acid (plant plane), or Piercing (earth/metal plane).

Elemental Glyph. Aniela puts a hidden glyph on a surface she can see within 10ft. she casts the glyph of warding spell (explosion only) as an action. The damage depends on the plane she is channeling; fire (fire plane), cold (water plane), lightning (air plane), acid (plant plane), or thunder (earth/metal plane) this ends her channeling.

Summon elemental. Aniela casts summon elemental as an action. the elemental matches the element of the plane she is channeling and does not require concentration to maintain. Aniela can only have one elemental of each plane summoned at a time.

Eye of Silvra (Recharge 5-6). Aniela creates a miniature sun at a point she can see within 500ft, this sun takes up a 10 foot square and casts bright light for 500ft and dim light for another 500ft beyond that (this light counts as sunlight). a creature inside the sun must make a constitution saving throw or take 21 (7d6) damage on a failed save, half on a success. As an action on subsequent turns as long as she concentrates on the sun she may expand it by 5ft in every direction and move the sun up to 30ft in any direction. any creatures of her choice within the suns light add 1d6 damage to any attack they make or spell that does damage relating to the plane she has channeled they cast. (fire plane; fire. water plane; cold, bludgeoning. air plane; lightning, slashing. earth plane; necrotic, bludgeoning. plant plane; piercing, acid. metal plane; piercing, slashing.) this ends her channeling and, The sun lasts for up to 1 minute or until she loses concentration. (while true conflux is active she may choose any of the damage types when she summons the sun, but the added damage is applied to any of the damage types.)

Channel plane. Aniela channels a single elemental plane allowing her to use its abilities, and an aura with a radius of 30ft centered on her that gives her benefits depending the plane channeled.

Planar Aura. As a bonus elemental wings sprout from her back. this lasts until she dismisses it or an impulse dismisses it. While channeled enemies within her aura lose resistance to the damages associated with the plane currently channeled, and Aniela gains additional benefits depending on the plane channeled;
