THE FLYING SPAGHETTI MONSTER (Warlock Patron)
Once upon a time, you were arguing with your good buddy Jethro. Jethro was a "Warlock" of an "Archfey". He was arguing with Jethro, because only Jethro had supposedly seen his Mistress, and she was otherwise unseen, unfelt, and her existence was impossible to prove. Any test you could imagine he had an excuse for. "She doesn't like being seen." "She won't appear in front of non-believers." "I'm not an academic or a Priest, where else would my magic come from?"
The gist of your argument becomes "Anyone could declare themselves a Warlock and gain magical powers then. I could say "I'm a Warlock of the Flying Spaghetti Monster." and, boom, supernatural powers." Jethro wasn't exactly happy with this state of affairs and dared you to try it. So you wrote up an entire description of your "Master" and it's intentions, and what powers it granted you. Everyone thought it was funny until it worked.
Suddenly, people who called themselves "Pastafarians" had access to magic granted by an invisible, immaterial and un-provable being(s), with no apparent oversight. This led to some concerns. If any one could declare they had a set of powers granted by a mystic being for agreeing to follow it's particular ethos, and then it never appears to intervene, even for violations of that ethos, then something was severely bad with reality. So you plunked a pasta strainer down on your head and set out to find the truth.
EXPANDED SPELL LIST
At 1st Level you choose from an expanded list of spells when you learn a Warlock spell. The following spells are added to the Warlock spell list for you.
Spell Level Spells
1st: Ceremony, Magnify Gravity
2nd: Blindness/Deafness, Blur
3rd: Nondetection, Pulse Wave
4th: Evard's Black Tentacles, Greater Invisibility
5th: Mislead, Modify Memory
HEADGEAR
At 1st Level, you may opt to adopt a pasta strainer, or similar metal dish, as a helmet. This headgear increases your AC by +1. Not only that but you may gift it to another, who can gain the same benefits once it is attuned by them (you must attune as well if you are keeping the headgear). You create a maximum number of helmets equal to your Warlock Level divided by 4 (round down, minimum of 1).
PIRATES ARE COOL
At 1st level, you learn the Message and Vicious Mockery cantrips while hanging out with pirates. They count as warlock cantrips for you, but they don’t count against your number of cantrips known.
WALK UNSEEN
At 6th Level you can now cast Invisibility as an Action, Bonus Action, or a Reaction to being attacked. You must cast it with a spell slot to be able to use this ability. At 10th Level you may also do this for Greater Invisibility.
YOU CAN'T PROVE THAT
At 6th Level you are such an obstinate debater that you become immune to being Charmed.
GRAVITY ARCANUM
At 10th Level, you may switch you may exchange any spell you have taken from Mystic Arcanum for a spell of the same Level from the following list: Gravity Fissure (6th), Etherealness or Reverse Gravity (7th), Dark Star (8th), or Ravenous Void (9th). As you gain each new Mystic Arcanum, you may opt to choose from this list as well. Additionally, all spells you cast with spell slots that do Force damage have their Save DC (if any) increased by +1.
TRUTH BOMB
At 14th Level, you may, as an Action, argue that a particular creature within 60 ft. of you doesn't exist, and if it fails an Intelligence Saving Throw against your spell save DC, the target ceases to exist for 1 Minute. Creatures must be able to hear and understand you, so they must share a language you speak. No one can see the target creature, touch it, or affect it in any way, nor may it affect them in any way. For all intents and purposes, it ceases to exist for 1 Minute, and it reappears in the same square it occupied when it disappeared when the minute has run it's course. this can be used a number of times per Long Rest equal to your Proficiency Bonus.
