Constructs in D&D. (These others could likely be used for AD&D as well.)
A construct is a monster that is not actually alive, but which has been created magically. A Lesser construct is costly to make, and can be hit by any weapon. The Lesser constructs in the D&D system include iving statues (Basic Set), magen (game adventure X2), and juggernauts (X4).
A Greater construct is very expensive, but can only be hit by magic weapons. The Greater constructs include gargoyles, golems, and drolems .
The following general rules apply to all constructs:
- They can be created only if the proper magical process is used. This often involves a special book, libram, or tome, plus special materials (which must usually be purchased), certain spells, and time.
- The time needed varies by the size and power of the construct, but is never less than a week, and may be greater than a year.
- They do not heal normally; magic must be used to cure them of any damage incurred.
- They are immune to the effects of poison (since they are not truly alive), and mental effects (charm, sleep, illusions, etc.).
- They do not reproduce; there are never “baby gargoyles,” for example.
- The DM may add special treasures (such as a book of gargoyle creation) if desired. Player characters may wish to use constructs to help guard castles, dominions, or special treasures.
