A few changes:
- Earthquake will no longer be felt in an entire zone. Instead, the effects
will propagate somewhat like a "yell", with different messages being given
according to distance and intensity.
- Area-effects, like portal, darkness and watch room, and door-effects,
like block/break/bash door, have been detickified: they can expire at any
- If you know detect magic well, you will be able to sense if there is a
portal leading to your current location. If you know detect magic very
well, you will also get a "locate" key to the other end of the portal.
