"Domain" refers to an area, city, guild hall, or part of a world in 
RetroMUD. This division is used exclusively for calculating exp penalties 
from death. Any penalties for one domain apply to all rooms that share 
that domain and have no effect outside them. For more information on how 
these penalties are obtained, see: HELP RESURRECTION.

The penalties in a domain affect all exp gained in that domain. These 
sources include exp from killing, quest rewards, exploration, and so 
forth. If you have a penalty of 10, you get 10% less exp, etc.

If your penalty reaches 100, you earn no exp, and you and your party 
members cannot damage any mobs in that domain. Exploration still 
accrues, even when it does not reward exp.

To view the domain of your current room, type "show domain". To view your 
current exp penalties from death, type "show penalties".

Domain penalties expire at boot.
