Chaotic Everywhere (CEv): These players cause heartache to many a DM and player alike. A Chaotic Everywhere tries to be everywhere and do everything at once. His PC is usually the first person in a room when treasure is discovered and the first out of a room if trouble occurs. Often, such a player is impatient and is nearly always a source of interruption especially when the rest of the party is doing something or the DM is describing more than one object in a room.
Example: A group of adventurers containing a Chaotic Everywhere character comes upon a room that is set up like a chemist's lab. The Chaotic Everywhere moves all over the room, showing up whenever another adventurer finds something of interest. The person then tries to do anything in the room that someone else was planning to do. If the character in question creates an explosion with some chemicals, the player claims no damage was taken because he ran at the first sign of trouble.
The best way to get revenge on this type of person is to get the whole party to threaten the Chaotic Everywheres character with death, or for a DM to design an enclosed room that floods when entered, making sure that the Chaotic Chaotic Everywhere is the only one to go in.
