Nicklaus' Instant Workshop
Wondrous Item
This palm-sized figurine resembles a folded toy workshop carved from polished pinewood and decorated with tiny painted windows, silver runes, and miniature shutters. When shaken, it emits a faint jingling sound and smells of fresh sawdust, warm oil, pine resin, and peppermint.
When placed upon the ground and its command word spoken, the figurine unfolds and expands over the course of 1 round into a fully equipped magical workshop.
The workshop occupies a 20-foot-square area and stands approximately 30 feet high, complete with chimneys, workbenches, tool racks, storage lofts, reinforced doors, and a permanently warm hearth.
The entrance always faces the item's owner.
Workshop Structure
Each exterior wall has:
AC: 18
HP: 100
The doors and shutters are reinforced hardwood bound with iron and may be locked from within.
The workshop is a magical structure and receives the normal saving throws of a magic item.
Unlike an instant fortress, the workshop is not intended as a defensive stronghold and does not extend foundations deep into the ground. It must therefore be deployed upon reasonably stable terrain.
I like AC 18 here rather than the original 15. C&C magic objects tend to be sturdier, and the structure should still be substantially easier to breach than an adamantine fortress.
Artisan's Haven
The interior contains magically maintained examples of most ordinary crafting equipment: benches, clamps, anvils, small furnaces, carving stations, sewing frames, basic measuring implements, and similar tools.
A creature using an appropriate craft, profession, or artisan ability within the workshop receives a +4 bonus on checks related to crafting, repairing, or evaluating manufactured goods.
This bonus does not grant proficiency or specialized knowledge the creature does not possess.
That is the conversion I prefer for the original “advantage.”
Efficient Crafting
The workshop's enchanted tools, perfect lighting, self-heating furnaces, and magically organized workspace greatly accelerate mundane labor.
Any nonmagical object constructed or repaired entirely within the workshop requires only half the normal amount of time, to a minimum of 1 hour.
This does not reduce the cost of raw materials.
Magic-item creation is not accelerated by this property unless the Castle Keeper specifically allows it.
I would explicitly keep magical crafting outside this benefit. Otherwise this one item starts interfering with C&C's entire magic-item creation economy.
Warm Hearth
The interior remains pleasantly warm regardless of ordinary exterior cold.
Creatures resting or working within the workshop are protected from natural extreme cold and receive a +4 bonus on Constitution saves against magically induced cold weather or similar environmental exposure.
This protection does not grant resistance to direct cold attacks, spells, breath weapons, or similar effects.
Toymaker's Magic
Once per day, the workshop's owner may activate its greatest crafting enchantment while standing inside.
This ability functions as fabricate, but may affect only ordinary:
-
wood
-
cloth
-
leather
-
iron
-
steel
-
copper
-
brass
-
or similar common crafting materials.
The effect cannot create magical items, alchemical substances, precious gems, coinage, special materials, or objects requiring craftsmanship beyond that possessed by the user.
For purposes of this ability, treat the effect as though produced by a 9th-level caster.
That restriction is important. The workshop should feel miraculous without becoming an automated source of mithral plate, jewelry, or free treasure.
Folding the Workshop
The owner may speak a second command word while touching the workshop.
At the end of that round, the structure folds inward upon itself and returns to figurine form.
The workshop cannot fold while creatures remain inside.
Any unattended mundane objects that belong to the workshop—benches, tools, furnishings, and so forth—fold away with it. Objects brought into the workshop do not disappear into extradimensional storage and must be removed first.
I would change that from the original automatic ejection. The C&C Instant Fortress specifically cannot be deactivated unless empty of creatures, and I think borrowing that restriction makes this feel considerably more native.
Damage and Recovery
If one or more walls are damaged, that damage remains when the workshop is returned to figurine form.
Mundane repairs may restore damaged walls at the Castle Keeper's discretion, provided proper timber, iron fittings, and skilled labor are available.
If the workshop is reduced to 0 hit points, it immediately collapses into its figurine form and becomes inert.
After 7 days, its magic restores enough of the structure for it to function normally again.
I would keep your seven-day self-restoration. This is one of the places where I would deliberately make it more forgiving than the actual Instant Fortress, because C&C's fortress is extremely harsh: damage to it can normally only be repaired by wish.
That severity suits an adamantine siege tower. It feels unnecessarily punitive for a whimsical portable workshop.
Deployment Hazards
Unlike an instant fortress, Nicklaus' Workshop expands carefully around nearby creatures and objects.
If insufficient space exists for the structure to deploy safely, activation simply fails.
This is another distinction I would preserve deliberately. The actual Instant Fortress can deal 10d10 damage to creatures caught in its sudden expansion.
Nicklaus did not build his workshop to pancake the apprentices.
Value
I would peg it at approximately:
GP Value: 30,000 gp
XP Value: 4,500 XP
Notes
- Created by the mysterious and powerful magical Nicklaus or Nicklaus the Red, the instant workshop is a marvel along with Archmagi Daern's Instant Fortress. Simply place the workshop and speak the command word in order to create an a Artificer's dream of a base and foundry.
- Is a replica of THE workshop used by The Toymaker of the North in order to fabricate toys and decorations for the festive months of the Known World.
- Only one of the instant workshops has fallen to an evil servant of the Toy Maker, and it used to create bad versions of toys to be given over to naughty children of the Known World.
