"Spheres."
Seconded...although they were a bit fiddly.
"Spheres."
That said, I do like the idea of differentiating clerics of various gods with spell choice. Each god should have sets of spells that are forbidden, weakened, normal, and augmented.
ugh...If you're doing that, just give each deity a different spell list and alter spells levels appropriately. If a deity has unique spells, so be it.
I basically agree, but I think that shows how you find a solution.
If you don't have anyone on hand to pick a lock, you pass by the door, maybe beat it down, maybe cast a spell like knock, maybe beat up some guards and take their keys. There's more than one way to get through a locked door.
If you don't have anyone on hand to remove your curse...historically, in D&D, that has meant that you're just cursed and it sucks to be you (NPC spellcasters can maybe help). But if there's multiple ways to deal with curses -- kill the critter that gave it to you? Make a few saving throws? Fullfill some requirement of it? -- if the curse isn't instantly utterly debilitating, that's gonna be a world where you don't have to have Remove Curse to function, but it can still be useful.
My point is that the 3e cleric removed restrictions that were there in 2e. This allowed access to a much wider range of spells, for all clerics that previously.2E clerics are not really any more restricted than 1E. In 1E, clerics and druids had separate spells lists with a bit of overlap. In 2E they combined the lists into one big list then divvied access up with "spheres," with clerics and druids getting about the same spells they had previously; this also gave them a mechanism for easily creating spells lists for the optional specialty priests, which worked pretty well.
So if clerics in 1E, 2E, and 3E all had unlimited spell lists, and only 3E had a problem with overpowered clerics and druids, that suggests that the problem was not the unlimited spell lists.
I've no objection to restricting spells to create specialty clerics akin to 2E's. They're a whole lot more interesting than generic clerics. But it hardly seems like a high-priority issue.
I have noe idea why you are saying that "So if clerics in 1E, 2E, and 3E all had unlimited spell lists" when you know that wasn't the case. It was limited by spheres in 2e (which is in the post you quoted)
I wonder if we could manipulate the current spellcasting model. At the moment you select a number of spells to prepare at the start of the day (or pray for I suppose), and then you can cast those as you please, even at various levels.
If spells were somehow classified, into exclusive spheres, or non-exclusive domains, or using keywords, then for each deity we just need to know how they feel about each of those categories. I imagine that one or more might be favoured, some disfavoured and perhaps others are even forbidden. Spells from disfavoured spheres could cost two of your preparation slots, compared to one for favoured spheres. Obviously forbidden spheres would be unpreparable. You might even (for very magical deities) have a sphere that's always prepared for free.
This way, your standard deity of fire can be unconcerned with the removal of disease, but one of their clerics can still prepare it by expending an extra slot. Said cleric probably never gets to prepare create water, however.
