The Morrigan

Your patron is The Morrigan, a powerful Fey deity who embodies fate, death, and war. Also known as the Queen of Banshee's, The Morrigan sends out her followers to warn those of their impending doom at the hands of fate. 

Twister of Fate

Starting at 1rst level, you gain the ability to alter the fate of others as well as yourself. You gain a number of d6's equal to your charisma modifier (minimum of 1). You can add any of these d6's to any attack roll, saving throw, or ability check made by you or a creature that you can see with one of these fate rolls. You must choose to do so before the roll, and you can expend one die in this way only once per turn. These dice become d8's at level 6, d10's at level 10, and d12's at level 14. You regain all expended uses of your fate dice after you finish a short or long rest. 

Visions of Death

At 6th level, you learn to magically fill a creature's mind with a vision of death. Any creature within 60 ft of you must make a Wisdom saving throw. On a failure, the creature takes 4d6 psychic damage and is now frightened for 1 minute as their minds are plagued by the paranoia of doom. The creature can remake the saving throw at the start of each of its turns, with a success ending the effect. If the creature succeeds the saving throw, or the effect ends, the creature is now immune to this effect for 24hrs. Once you use this feature, you cannot use it again until you finish a short or long rest.

Cry of the Banshee

At 10th level, The Morrigan bestows upon you the power to release a mournful cry that marks your enemies for death. All creatures within 30 feet of you must make a Constitution saving throw. On a failure, the creatures take 2d10 psychic and are now under the effects of the Hunters Mark spell and are deafened. The creatures only take half damage on a success and are not deafened or marked. Once you use this feature, you cannot use it again until you finish a short or long rest. 

Sealed Fate

At 14th level, your mournful wail becomes more lethal to all who hear it. The range of the wail is now extended to 40 feet. All creatures within that range, on a failed Constitution saving throw, immediately drop to 0 Hp and die. Any creature who succeeds the saving throw will take 2d10 psychic damage, become deafened, and fall under the effects of the Hunters Mark spell. Once you use this feature, you can't use it again until you finish a short or long rest.
