The Senpai

Some patrons barely notice the subjects of their pact. Some patrons view their subjects transactionally. Some patrons take an unhealthy interest in their counterparts intimate details and life. Some warlocks do, too.

Expanded Spell List

Your eternal pact with Senpai, even if Senpai doesn't know it, allows you to choose from an extended list of spells when you learn a new spell. The following spells are added to the Warlock spell list for you.

Mad (-ly in) Love

Starting at 1st level, you choose Senpai as your patron, you are able to harness your affection to bolster your physical abilities to a near-supernatural level. You gain the following features to better "protect" Senpai.

• Amour Armor: While you are wearing no armor and wielding no shield, your AC is equal to 10 + Dex modifier + Cha modifier. 

• Basic Instincts: When you wield a one-handed slashing or piercing weapon, it gains the versatile property and deals 1d10 damage if used in both hands.

• Who Dates Wins: When you deal damage to a surprised creature or take damage while surprised, you gain temporary hit points equal to your Cha modifier + your warlock level

Mad (lyin) Love

At 1st level, you have advantage to deception checks to lie to yourself

(Don't) Notice Me Senpai!

Starting at 6th level, you have become adept at avoiding Senpai's rejection attention, and you apply that talent effectively. 

As an action, you can concentrate (as if on a spell) and become invisible for up to 1 minute, choosing a creature you can see within 30ft of you. This invisibility ends early if you make an attack, cast a spell, or end your turn more than 30ft from that creature. You can use this ability a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

I'm Not Crazy, You're Crazy

At 10th level, it is nearly impossible to shake you from your feelings and your vengeance against those who would turn you against Senpai is swift and brutal. You have advantage on saving throws against effects that would charm or frighten you, (unless that effect comes from Senpai, of course).

If you succeed on such a saving throw, you can use your reaction to reflect the effect back onto the originating creature, if one exists. It must succeed on a Wisdom saving throw with the same DC as your Spell Save DC, or be charmed or frightened (your choice) of you for one minute. The creature may repeat the saving throw at the end of each of its turns, ending the effect itself on success.

Determinator

At 14th level, you know in your heart that Senpai will love you, and only you, forever, and the strength of it allows you to hold on in even the most terrible circumstances. 

As a reaction, to being reduced below half your total hit points, you can immediately gain temporary hit points equal to your warlock level. If you are charmed, frightened, paralyzed, or stunned, the condition ends, and if you are prone, you can stand up as part of your reaction. On your next turn, you can take one additional action that must be used to attack or cast a cantrip with a casting time of one action.

Once you have used this ability, you cannot use it again until you have finished a long rest.
