it is easy to finish many puzzles exept this mirror room. if you have any idea pleace contact me

Can you give us more detail on what you are stuck on?

I think that is a plenty of detail, well the idea is that the mirrows reflect their ligth onto the Simbol thats in the altar, here it goes take the left mirrow that is to the left now move it unil it reflects the ligth of the 1st mirrow, the next thing that you should do is make the reflected ligth goes onto the bottom wall now take the mirrow hat is similar to the one you alreday used and put it in a way that the ligth is reflected once again now use the last mirrow to reflect the last ligth, BTW if this work jut change the bottom mirrows and adjust them to make the seal be iluminated and reclaim the supreme sword of POP:SOT
