Ok im finally at the Wizards Tower, but im stuck on the Mirrors. Im going in circles i think. Its either left or right

You have to pay attention to what the room descriptions are.

Each room has a colour, and each room has a left and right mirror. For each room, the two mirrors have set outcomes.
For instance, the Amethyst Room's Left mirror goes to Emerald room, while the right goes to Sapphire. Jade room's left ALSO goes to Emerald. Silver's Right also goes to Sapphire.

You can write down and make a chart for yourself, working out "X room Left = Y room, Y's left = Z room" etc, and at some point you either end up in the right place by coincidence or by process of elimination (but if you end up on the right path and then pick wrong you know how to get back)
