I need to remove/change the level requirements on the Daedric quests that have them, but I can't find in either the CK entries nor the scripts where it says what the level requirement is. Often there is no discernible reference to level requirement at all.

Does anybody know where I can find, and change, this?

Only 9 of the 16 Daedrics have level requirements, so make sure you are looking at the correct quests.

I know that, thanks. Not all the quests are linked to on level increase event node, and on those that are I can't find any reference to the actual level required in the script.

There is a semi-workaround for Boethiah's Calling in that Boethiah's Proving can be set to 1 in the leveled lists, but other than that I'm at a loss.

EDIT: I found that most, but not all, of them are associated with a global variable DA02MinLevel etc, although some of them still require a level up event (The problem being that my mod removes leveling entirely).

The work through the SM to initialize, so you could just make them Start Game Enabled instead I think.
