Minor Warlock

You have made a pact with an otherworldly being in order to get more power. You gain the following benefits:

• Choose an ability between inteligence, wisdom or charisma, the one you choose is your minor warlock spellcasting ability. Any warlock spell or warlock feature granted by this feat that may use your charisma as a spellcasting ability or refers to your charisma, may instead use your minor warlock spellcasting ability.
• Choose an otherworldly patron from the warlock's Otherworldly Patron feature's list. You gain the 1st level warlock feature granted by that otherworldly patron. If a feature refers your warlock level, your warlock level equals to a quarter your character's level rounded up.
• You learn the Eldritch Blast cantrip.
• You learn the Hex spell and you may use it once at its lowest level without expending a spell slot, you regain this use after you finish a short or long rest.
• You have a number of eldritch invocations acording to your level: one at 1st level, two at 5th level, three at 11th level and four at 17th level. The level prerequisite of an eldritch invocation, refers to your character's level. Whenver you gain one level on any class, you may change one eldritch invocation you have with another you could have at the current level.
• You gain access to one pact boon of your choice, it must fit your otherworldly patron (by instance: you can't have the star chain boon if your patron is not the seeker).
