Azareck's Demonic Aspect

Utter the words of power to be overtaken by the power of the Abyss. You gain the following buffs:

• You have resistance to Fire, Lightning and Cold damage.
• Boundless Intellect - if you would take Psychic damage or something that would charm or frighten you and you succeed on the save, the originator must make a Wisdom saving throw against you spell DC and on a fail they take the damage you would or they are charmed or frightened.
• Drowning Presence - creatures within 10ft of you who cannot breathe underwater are considered choking and magical, inky black water fills their lungs. A creature can go without air for a number of rounds equal to their Constitution modifier (minimum of 1), at which point they take 15d6 Magical Bludgeoning that ignores resistance and immunity. If this happens twice they instantly fall unconscious. Creatures cannot regain hit points while within 30ft of you (excluding yourself and allies of your choice).
• Maddening Presence - creatures who are in you line of sight or who can see you must make a Wisdom saving throw at the beginning of their turn. On a success they take 3d6 Psychic damage and they're immune for the next hour. On a failure they take 6d6 Psychic damage and gain a trait of Short Term Madness. They repeat the save at the beginning of each of there turns, and on a fail they take 1d6 Psychic damage and stay mad. If they pass they're immune for the next hour.
• Your melee attacks count as magical, when you take the attack action you can attack twice, your unharmed damage increases to 1d8, and you gain a +2 to melee attack rolls and damage rolls.
• You're immune to critical hits.
• You perform critical hits on a 19-20.
• You have advantage on Charisma ability checks and Wisdom saving throws.
