World/Area random events

Thanks a lot, glad you like them :-)
Those rare mobs are a must imho.
or spawn if the proper ritual is accomplished.

Some more events I added in my NWN2 mod: planar gates.
Sometimes, planar gates would randomly spawn in the world (think RIFT stuff, but much more random). Stuff would get out of it (creatures).
Tied to a skill of course, elemental learning, or magic reading, or whatever. basic reading would give experience, or magical elements to create items or whatever, and a legendary practitionner was able to "read" this gate, and open it, to go to the plane itself, that would be very dangerous, but full of treasures. Could be tied to some world surprise. The player has no ideas he can cross into another plane, until he actually does it...
