Creature Dwelling refers either a building in a town or a structure that can be found on the adventure map. They are living places of creatures that can be hired. Each dwelling produces a unique number of creatures each week. In towns the growth is cumulative, which means that the creatures not hired will remain in the dwellings. In adventure map dwellings the number of creatures cannot exceed the weekly growth. Also, a hero must visit the dwelling in order to recruit the creatures while a player can hire creatures from town dwellings into town garrison. However, in the Horn of the Abyss , the growth in the adventure map dwellings is also cumulative. For example, owning an external Warren whose growth is +14 will allow to get up to 28 Troglodytes on the second week, 42 Troglodytes on the third, etc. The month of plague, which is affecting internal dwellings only, in Horn of the Abyss halves the amount of creatures in flagged external dwellings as well.
Only non-upgraded creatures can be hired from the adventure map dwellings. The exception is Golem Factory, which provides Iron Golems in addition to Stone Golems, as well as Gold Golems and Diamond Golems both of whom are neutral creatures. Interestingly enough, the graphic representations of most of the external dwellings resemble the corresponding upgraded town dwellings, despite yielding only non-upgraded units.
The cost of creatures is the same as in towns and adventure map, except level 1 creatures, which are recruited for free from adventure map dwellings. Once the dwelling fly under the player's Flag, all associated dwellings in towns receive +1 growth bonus. For example, flagging a Centaur Stables will provide +1 for Centaur and Centaur Captain growth in each Rampart the player owns.
In addition, on the adventure map creature dwelling of level 5, 6 and 7 are guarded by non-upgraded versions of the creatures the dwelling produces. The number of creatures is growth times three, which means that level 7 dwellings are guarded by 3 (with exception of Pyre guarded by 6 Firebirds), level 6 by 6 and level 5 by 9 creatures. The guards are renewed at the beginning of each week, which means that the dwelling may be re-flagged for free by enemy heroes any number of times during that week. Pre-flagged dwellings are guarded for the enemy at the first week. If a hero retreats or is defeated, only the surviving guards will be there if another hero attacks in the same week.
