Twilight God of Might and Victory

God of Might: Kain's power explodes, his Strength Score is set to 30. Kain's resistances and immunities cannot be bypassed, suppressed or changed. Kain adds his proficiency to the damage and allies in his aura may add Kain's Charisma Modifier to their attack roll. Kain treats AC above 40 as 20 and his melee weapon attacks are capable of destroying barriers and creations of magical force. Kain can make 2 additional attacks when taking the attack action and use his rage without consuming charges and only ends when he chooses to end it.

God of Victory: Kain becomes one with Vera's Soul and no longer needs to attune to it. Its power evolves and he may summon the souls of his allies without the Banner as a Bonus Action. Unless Kain chooses to be affected, Kain is immune to Wish and spells of 3rd level or lower (3rd level spells and below upcasted are still considered their base level) unless he chooses to be. Kain's aura is an extension of his domain, allowing his abilities to be active at all times, unable to be bypassed, ignored, suppressed, disabled, copied or stolen.

God King Commander: Kain can freely change the his type of his damage. Kain gains immunity to all damage from non-magical sources. Kain and his allies in his aura are protected from being affected by antimagic, regardless of outside effects, conditions or spells. Kain is unaffected by attacks, spells, conditions and effects whose save or check DC and/or damage is 20 or lower. Kain may add his Charisma Modifier to Checks. All hostile creatures that start their turn or enter within 60ft of Kain reduce their current hit points equal to double Kain's Charisma Score.

Absolute Duo: Kain can designate one friendly creature to be his "Valkyrie/Vanguard". Once chosen, they are always considered to be in Kain's aura, their walking speed matches Kain's, may add Kain's charisma modifier to checks, gain 2 additional attacks when taking the attack action and they have access to his ability, "The Goddess Engine". They remain like this until Kain chooses to end it, they die, Kain dies or they become hostile to Kain. (Kain must be on the Quest).

Fragment's Presence: Kain's mighty presence is enough to rattle the battlefield. In order to impose one's own will against him, any hostile creature who targets Kain with an attack, effect, check or spell must first succeed on a Charisma Check DC equal to Kain's Charisma score. On a failure, the creature must choose a new target or lose the attack, effect, check or spell. If Kain is conscious at the start of his turn, he can choose to remove 1 effect or condition affecting him. Additionally, Kain can take legendary actions, choosing from the options below. Only one legendary action can be used at a time and only at the end or start of another creature's turn. You regain spent legendary actions at the start of your turn.

Assault (1 Action) - You take the attack action.
Advance (1 Action) - Move up to your movement.
Blink (1 Action) - Teleport up to 60ft to a spot you can see.
Unyielding (2 Actions) - End 1 effect, condition or ability of a creature within 60ft of you.
Benevolence (3 Actions) - Replenish your entire "Lay on Hands" Pool.
Unrelenting (3 Actions) - All allies Ignore enemy resistances and treat immunities as resistance, until the end of each of their respective turns. 

Legendary Resistance (1/Day): If Kain fails a saving throw, he can choose to succeed instead.
Legendary Performance (1/day) - If Kain would fail a skill check/contest, he can instead choose to succeed.
