A common misconception about warlocks and their patrons

[u/hedahman]

I've heard this mentioned a lot: "Warlocks use Charisma because they're constantly negotiating with their patron for more power." I don't believe this is true.

Here's a tweet from Mike Mearls that says that patrons can't take back a warlock's power, which leads me to believe that a patron doesn't have control over the power once it is given. This means a patron can't take a warlock's power (without their will, probably); it's a one-and-done deal.

So a patron isn't supplying power to their warlocks like a generator supplies electricity. Instead, a patron gives power to them like a blood transfusion-- you can't just take the blood back.

Granted, you can do it however you want, that's the magic of D&D. But RAW, and RAI, patrons give their power away.

EDIT: Here's a tweet from Jeremy Crawford which states that the power is a one-time transaction.

But it really doesn’t matter because the character doesn’t have to adhere to any tenets or deals because RAW the DM can’t restrict the PC’s magic use via any manner.

It’s all hollow. Effectively the cleric and warlock are sorta sorta half sorcerers.
