Hello, I've recently started to think about getting into speedruning some of KH2. However I was wondering if using the unlock all synth items mod was allowed to bypass the time for farming Megalixirs for the Data Org fights. Is this ok in the non-modded categories as it's being used as simply a time save and not affecting gameplay directly?

I want to reiterate that this is only for the Data Org/Terra/Sephy not the main game.

Modding Mega-Elixirs is fine! As long as the gameplay is the same you can mod any item that would be in the main game (except for removing keyblades for example to make menuig faster/shorter)
