Stamets [Mirror]I don't care. Eldritch Repo folks are being sent
TwilightVulpineI don't think it's great for any class to take back powers that the character has earned. Not even clerics. For as long as there have been religions, there have been schisms and power plays. It even ruins possible intrigue involving religions if you can tell what follower of a good god has gone astray by asking them to cast a spell.
There are more interesting ways to do consequences for defiance of higher powers than to hold their abilities hostage. That feels less like the consequences of a living world, and more like the DM yanking the player's leash.
But I can accept that this is an established system/setting thing for clerics and paladins. For warlocks, it is not.
I like the idea of the cleric being required to do some kind of penance, on the threat of losing their powers.
In general, you don’t want a player to loser their powers. But if you can turn the threat of losing their powers into a plotline, then that’s awesome. Warlocks losing powers for breaking contracts is bad. Warlocks having to fend off eldritch repo folks for breaking contracts is good.
