What is the deal? I'm lvl 100, used it, it showed up down on the bottom right corner of my screen but I didn't get to go to the temple of fiends. Whats going on here?

when it says you can now enter. you need to go to guard captain and choose the option to go to the labyrinth or else it wont work

Yeah but dont die, u lose exp. if youre 112, dont go in here..... just a tips
or if you go there, buy some 90%
