These help add atmosphere to the dungeon, such as having items in alcoves instead of scattered on the dungeon floor; a slime trail along the floors and wall leading to a possible source; an empty cobweb suggesting some eight legged fiends could be lurking about, pipes and machinery connecting to something even more diabolical.
Decorations may be placed almost anywhere in the dungeon and they come in a range of shapes and sizes.
Placing a Decoration
Right click Edit on the floor or wall tile, Add new select the floor or wall object you desire.
Associated with Triggers
All decorations could be a trigger, causing an addition effect somewhere else in the dungeon. See Triggers for more information.
