Okay so instead of the usual way of MR series.. make the whole idea based on a tournament for this part.

Where Berlin was captured and a large cult of evil like people like hold a tournament to see who gets to do tourturous things to Berlin... or in Merlin's case.. set him free.

like have a massive tournament thing of 356 total competing teams or solo competitors, and have each ladder Different as well as letting the players decide what ladder they want to enter.

as for the potions and health thing.. make a gold thing or something and a shop so the players make merlin stronger by purchasing the things they want to have for him.

and have the enemies themselves get stronger as the game goes with the rank system like last time you had, and please don't make it pre- determined, have all the different teams randomly placed if you can manage that Okay?
