I've cleared zerobilon up until the last protal (the one with the barrier).
Does the Energy Stone give anything else other than the two potions when consumed?
Also there is a passage in the "Request" document found in the coach (on the table under the lever) that mentions fire traps and "Lockpicks that no lock can resist!". I'm assuming this reference is about a Skeleton Key possibly found as loot within the tower. Has anyone found it / does it exist?

It doesn't. It was killed by our balancer.

Thank you for your prompt reply.
Awesome mod .
