I don't think you even need a detailed RAW explanation for why such-and-such a spell doesn't work (or why you should be able to break out of the main plot by level 3): it doesn't work because that's what the game says. My first experience of GMing was the Wildemount module Frozen Sick, and in the introduction text the players are told that there's a mysterious disease going round and none of the local clerics were able to cure it. The players all accepted it: this disease can't be cured by standard magic. If any of them had sat there going "but why doesn't Remove Curse fix it?!" all session, I wouldn't have bothered to run the game.
Agree, but it can still be fun to discuss about it on a forum.
@relogon : I'm not very familiar with 5E rules (am an old school DND player) so yea I didn't know the complete description of resurrection. (Seems like a game breaker to me at such a low level, but I guess that's also an old-school reaction)
You can (as DM) imagine what happens next after resurrection.
If they find someone to do it in act 1, the game is over. They will not be able to enter moonrise towers pretending to be true souls.
If they do it after killing Ketheric and obtaining his stone, how would the emperor react ? They don't need his protection anymore. They're free. Will he try to get that stone from them ? How will Gortash and Orin react when they arrive at Baldur's Gate, free from the tadpole. Are you still part of their plan to kill the other partner , or will they decide it's more opportune to kill you and get the stone.
And in addition, how would withers react to this "solution" ? He also has a greater purpose than just saving your lives.
Lots of choices for a DM to make.
