Traps can be either mechanical or magic in nature. They consist of a trigger and the scripts that apply the effect of the trap. Traps can cause damage, affect ability scores, apply curses, or cast spells.
Traps can be placed on doors, placeables, or the ground. They represent hazards for anyone who is not a "friend" of the trap; both hostile and neutral creatures can set off the trap. Traps that are placed with the set trap skill belong to the trap setter's faction, while traps placed by the module builder typically belong to the standard hostile faction (but can be placed in any faction). Door traps are triggered when either the door is bashed or the door is not locked and an attempt is made to open the door (the attempt fails and the trap is set off). Similarly, placeable traps are triggered when either the placeable is bashed or the placeable is not locked and an attempt is made to use it. Ground traps are triggered when the center of a creature enters the trapped area.
Typically traps would not respawn once triggered, but Cormyr has a respawning system that will cause dungeon traps to 'reset' after the dungeon has been unoccupied for a set time.
Setting traps is part of the repertoire of skills of rogues, rangers, and assassins. While anyone can disable their own traps, and disable traps up to a certain point, rogues are unique in their special affinity for disabling traps.
Trap crafting is highly custom upon Cormyr, see details here.
When a character is close enough to the trigger for a trap, that character makes a search check. (Close enough is 10 feet, unless the character is in detect mode or standing still, in which the range is 20 feet.) If successful, the trigger area is highlighted in red if the trap is hazardous, in green if not.
Cormyr and the Dalelands features an expanded list of epic traps to cover all vanilla trap types, adding epic spike, acid splash, holy, tangle, acid, gas, and negative to the base game's epic trap list.
