olympiad

Upon entering the stadium, the stat decreases. For example, a character has 1151 mdef, but inside the stadium, it decreases to 964. Does anyone know the reason?

Hello friends and folks! straight to the point: i have seen servers that have up to 150 olympiad stadiums so here lies the question: if let's say we have more available stadiums.... i duplicated 12 more stadiums in 17_11 map... is there a way they can be enabled to work in olympiad...
