Overall Notes - This subclass I tried to angle a lot of the features around being thematic to the patron bestowing power to the warlock. Generally I will try to get it to fit with the play style of the warlock though. Warlocks generally tend to be offensive casters that have an option to debilitate much like sorcerers. Their features do take a slightly more martial bend to them though.
Celestial (Heavenly Set) - This is a bit of an exception to the overarching, more selfish nature of warlocks. Celestial warlocks do provide some support and healing as one would expect of a creature from the higher plane, but they also excel at fighting against the forces of evil, slaying their targets with light and holy fire.
Fiend (Infernal Set) - To start off, I designed two sets for fiend. I will expand on the 'why' when I get to the Abyssal set. The Infernal set is fashioned after the devils of the lower planes and focuses on burning and torturing its foe. The legendary will be an ability I believe to be iconic to someone who makes a pact with a devil, which is a spell that makes a deal with the devil for a massive buff at the expense of losing your bonus action.
Fiend (Abyssal Set) - This is less of a set and more of an experiment on my end. I wanted to play around with random effects and it made sense to tie it to a demonic set since demons embody chaos and destruction. Demons are still fiends so I did not feel like it was ill-fitting, but if one is looking for a set built specifically for Fiend warlocks, one should look towards the Infernal Set. The set is built like a pseudo-barbarian set that focuses a lot on random effects and augmenting random damage types.
Great Old One (Harbinger Set) - A Great Old One is an alien entity that is incomprehensible to humanity. I figured this type of patron would likely provide powers that could mentally overwhelm and strike fear into a target. This is largely the goal of this set, providing benefits to psychic damage and ways to inflict and facilitate a mental breakdown on the target.
Hexblade (Dark Pact Set) - A martial set that will entirely focus on moving quickly and landing powerful hits on your target. This set focuses largely on landing first in initiative, landing more critical hits and channelling your force of will (i.e. your Charisma) through your weapon to devastate your targets.
