Those are 2 status that were to be in the game, but i dont know why they arent.
What did they do? I guess muddle just mess your controls but doom?
Why arent they in the game? Muddle probably was difficult to put on knights, I mean you can just change your controls and you are out of muddle but why isnt it like sleep that you cant almost never get it but mobs can?
Doom sound like really overpowered but i dont think that OOO made a status that just make you die
It is because when Recons use their ability you would inflict them Doom with 100% accuracy, which would make Lockdown unbalanced. I think that changed in the GBA version though.
They are implementing old things into the game (like Grimalkins) so maybe we will see new status someday. Doom would most likely be something really rare to see, like a very telegraphed boss attack.
