If you have Braccus' ring in your possession, the gargoyle at the main entrance will assume you ARE Braccus and teleport you completely past the maze.

if you bypass the maze this way, the gargoyle at the end of the maze will NOT reward you. It, like the other, simply acknowledges you as Braccus, and lets you into the tower.

I mean, why would Braccus get a reward for simply entering his own tower?

so, you MUST put the ring in a container somewhere else before speaking to the gargoyle. Found this out the hard way, after have been teleported by the gargoyle, then doing the entire maze in reverse.

so, if you got no reward, this is likely why.
