Blood Castle Devil Square

Ok, I m here with serious question, is there any way to change BC and DS level requirements? I want to make 150 max level in mu with low exp cooldowns on skills level requirements on items but it would look stupid if plate armor needs 100 lvl dragon 150 Black Dragon 200 and etc... so I want make it lower I've made everything for 150 max level server just need to change BC and DS level requirement, so anybody knows how? and its even possible?

should be easy to change the requirements in assembly, but then again it will 100% generate a ton of bugs
