Stronghold Parts

This page is useful for building a stronghold room-by-room, or for adding rooms to an existing structure.

Below are the various rooms and components. The choice of components dictates the purpose of the stronghold, whether it's a palatial home, military fortress, or arcane nexus. Many of these components are individual rooms, but some may be combined to build larger structures (for example, the Basic Tavern is about 400 square feet and can seat around 15 people ... but two units can be combined to produce an 800 square foot tavern seating 30 people; and the tavern can be made more serviceable by adding a kitchen and additional storage area).

Walls: Structures above ground are constructed with wooden walls by default, at no extra cost. Below ground walls are made of hewn stone at no extra cost. If other materials are used, additional fees can be incurred. You can select alternative materials from the cost modifiers below. More wall details can be found on our walls page.

Build Time: Building a stronghold takes one week per 10,000 gp of total price (if materials and laborers are readily available). Optional Rule: For every 10% extra that is spent, it takes 10% less time to build, up to a maximum of a 70% "rush charge" to get the castle built in 30% of the usual time. The DM may rule that some strongholds shouldn't use this optional rule. For instance, if your stronghold price includes a large percentage of wondrous architecture, you might choose to construct such items separately.

A small farm plot consists of modest fencing surrounding a patch of tilled soil, and the tools to cultivate that land (hoe, rake, a modest amount of crude fertilizer). Multiple plots can be purchased for a larger farm.

1 acre (200ft. x 200ft., 20,000gp) equals approximately 100 small farm plots. At least 4 laborers are needed to work 1 acre of land (1 laborer per 50'x50' sq. ft. worth of farm plots).

There are many modifiers that can affect the price of farm land, so the DM should use their best judgement when determining the cost. It is not very costly to buy a small farm plot in rural communities where land is plentiful (1gp per square foot). In cities, where land is scarce, the price can go up drastically (10gp-100gp per square foot). In addition, fertile land can cost more (+50%) than barren, rocky soil (-25%), and deserts cost the least (-50%).

Generally found only in dungeon strongholds, labyrinth components serve to confuse and bewilder foes, and perhaps trap them forever.

The marble floor has symbols inlaid that denote the section of the library in which you stand. The library includes two private study carrels and a number of smaller tables. A single large table allows a researcher more space to spread out texts or large maps.

A full-time librarian working near the entrance maintains a card catalog that indexes the entire library. This index cuts any research time here by 25%.

In addition to the typical librarian, you can employ one or more sages to provide assistance with knowledge skill checks (+2, DM discretion).

Prereq.: Guard (1)
This cell includes iron shackles on the walls and hay mattresses strewn about. You can shackle up to six Medium-size prisoners in a communal cell. Alternatively, you can replace the communal cell with independent jail cells. In this arrangement, each prison cell component includes two to four small cells each capable of holding one or two Medium-size creatures.

The standard prison cell comes with six sets of manacles capable of binding a Medium-size creature. For an additional 250 gp, you can replace these with masterwork manacles. To slip free of manacles, a character must make a Dexterity check (DC 20 or DC 25 for masterwork manacles). To break free requires a Strength check (DC 20 or DC 25 for masterwork manacles). A creature proficient with Thieves' Tools can pick the manacles' lock with a successful DC 15 Dexterity check. Manacles have 15 Hit Points.

A Small creature takes up half the space in a prison cell as a Medium-size creature. Manacles for Small creatures cost the same as for Medium-size creatures. Tiny and smaller creatures take up one-fourth the space, and their manacles cost 10 times normal. A Large creature takes up twice the space of a Medium-size creature, and a Huge creature four times the space. Manacles for Large creatures cost ten times the normal amount, and 100 times the normal amount for Huge creatures. Generally, you can’t keep Gargan-tuan or larger creatures in a simple prison cell, though by buying enough components you could get a large enough space. They require specially made manacles, which cost as much as 1,000 times the normal cost.

Basic units of measurement in DnD are based on creature size — a 5ft square can hold a Medium-sized creature. Below is a small chart showing basic units of measurement converted into square feet (with a square room's dimensions). Note: a 40'x40' room occupies the same square feet as a 20'x80' room, so a "square" doesn't need to be used when building.
