The Infinite

Some Patrons demand servitude; others demand worship. The Infinite demands nothing — it simply "is". A being for whom limits are an insult and boundaries are but illusions for the weak. The Infinite does not hoard its power - it shares it, pouring fragments of its endless essence into chosen vessels who dare to bear them.

But the mortal form was never meant to contain infinity. For every gift of might, a price is extracted — the slow unraveling of self, the stretching of one’s soul until it trembles on the edge of nothingness. The Infinite gives endlessly. And endlessly it takes.

This subclass is 2024 portable, just move the 1st level features to 3rd level

Level 1: More is more

Why settle for what others are given? I can give you so much more...

The Infinite demonstrates its generosity and excellence by granting you more than your mortal vessel should hold. Starting at 1st level, you gain an additional Pact Magic slot.

Level 1: Eldritch Battery

I give you velocity. I give you ruin. Batter your enemies with your newfound power.

Starting at 1st level, you can cast any Warlock cantrip you know that has a cast time of an Action with a Bonus Action.

You can use this feature a number of times equal to your Proficiency Bonus and regain all uses when you finish a long rest.

Infinity can wait

You have all the time in the world... Enjoy it at you own pace.

Starting at 6th level, you can cast either Slow or Haste using one of your Warlock spell slots. Once you use this feature, you can't use it to cast that spell again until you finish a long rest.

Additionally, you stop aging and you can't be aged magically.

Level 10: A taste of infinity

Ask and you shall have more. There is always more.

Starting at 10th level, your Patron allows you to make a request to tap into their power for a brief moment. You can use an action to regain up to half of your spent Pact Magic slots (rounded up). Once you use this ability, you can't use it again until you finish a long rest.

When you reach level 20, using your Eldritch Master feature also restores the use of this ability.

Level 14: Innumerable possibilities

More. More power. More knowledge. More of everything they said you could never have.

Starting at 14th level, the Infinite lets you enjoy their gifts more freely, but your finite body has to withstand the backlash. You can cast any spell of 5th level or lower using a Pact Magic spell slot. However, your current and maximum hit points are decreased by 30 for each spell cast this way. This reduction cannot be avoided by any means. You also have to provide the costly components if necessary.

If the use of this feature kills you directly, the spell takes effect normally for the full duration and you don't need to hold concentration on it, but the Infinite immediately claims your soul and you can no longer be revived by any means.

You can only regain a number of maximum hit points up to 10 times your proficiency bonus and only by finishing a long rest, as your Patron carefully restores your fragile existence. If your hit points are still reduced by this feature after finishing a long rest, you cannot use this feature until you finish another long rest.
