Path of Ceremorphosis Feat (Prerequisite: Level 4+)
You begin a symbiotic relationship with the mind flayer tadpole in your body. You gain the following benefits.
Ability Score Increase. Increase your Intelligence by 1, to a maximum of 20.
Mind Sliver. You learn the Mind Sliver cantrip. Intelligence is your spellcasting ability for this spell.
Psionic Power. The wellspring of psionic energy provided to you by your tadpole is represented by Psionic Energy Dice, which fuel the powers you have from this feat path.
You have a number of Psionic Energy Dice equal to your Proficiency Bonus. When you take this feat, your Psionic Energy Die is a d6. The die changes when you take feats along the Path of Ceremorphosis.
Any features in this feat path that use a Psionic Energy Die use only the dice from this feat path. Some of your features expend Psionic Energy Dice, as specified in a feature’s description, and you can’t use a feature if it requires you to use a die when all your Psionic Energy Dice are expended.
You regain all expended Psionic Energy Dice when you finish a Long Rest.
Psionic Overload. Whenever you deal Psychic damage, you can expend a Psionic Energy Die to roll the die and deal extra Psychic damage equal to the number rolled.
