Island Workshop
- See also: Isleworks Handicrafts
The Island Workshop is a building added with the Island Sanctuary in Patch 6.2 which provides a place for mammets to create handicrafts out of the gathered materials, produce, and animal leavings a player obtains on their island. Isleworks Handicraft production is the primary means of earning 
Seafarer's Cowries. The vast majority of activities in the Island Sanctuary funnel into workshop production.
Workshop Upgrades and Unlock Condition
Workshops are unlocked by following the Island Sanctuary tutorial questline at Sanctuary rank 3.
A hideaway can have up to two Workshops at Sanctuary rank 3, up to three beginning at rank 5, and up to four beginning at rank 15 (after Pathfinder Mk III/VI clears more plots).
Workshops can be upgraded. Upgrades cost various gathered materials and take time to complete (Earth hours). Each upgrade adds an additional 10% value to all items exported from that workshop: items made from a rank V workshop are worth 140% the value of items made form a rank I workshop.

Agenda Setting
Workshop agendas are set according to season and cycle. Each season corresponds to one real-life week and starts during the weekly reset (1 AM PST each Tuesday). Each cycle corresponds to one real-life day (24 hours).
In the top bar of the workshop interface, players may set the daily agenda of both the current season and the next season at once. In the current season, cycles that have already passed will be darkened out and unable to have an agenda set.
While each season has 7 cycles (days), only 5 of those cycles may be used to set a production agenda. The remaining 2 cycles must be set as a rest cycle, which will display as grayed out icons with a beach chair and umbrella in the top left bar. These default to the first and last cycles of a given season. However, players can change the rest cycles in the upcoming season. To maximize productivity, it is recommended that the first cycle of any season is set as a rest cycle, due to workshop mechanics (see below). It is not possible to retroactively change the rest cycles in the current season, even if a prior cycle had an empty agenda.
Players may assign a handicraft production agenda for each workshop based on how many workshops they have currently unlocked. The vertical time labels correspond to real-life time, divided by hours. Times that have already passed will be grayed out, while the current hour will be displayed in orange, and future hours in white. Players may only set an agenda starting from future hours. Each handicraft requires real-life hours (4, 6, or 8) to complete and must have sufficient time allocated in a given cycle. For example, it is not possible to commence a 4-hour craft starting at 10 PM (the craft will not "roll over" into the next day cycle).
Selecting Items
Players may select the items to craft by pressing the + button under a workshop agenda. This will bring up a new menu containing all handicrafts they have unlocked. These can be sorted by crafting time or by category (which determines efficiency bonuses). Each item will display information such as its base export value, popularity, supply, and materials needed to craft.
Additional handicrafts will be unlocked as the player increases their Sanctuary Rank and unlocks new Island Materials.
Copying Agendas and Using Presets
When setting a daily agenda for multiple workshops at once, players can copy agendas and use presets for convenience.
- Right-clicking on a workshop agenda and selecting "Copy This Workshop's Agenda" will copy the entire agenda. Players can then right-click on another workshop slot and select "Apply Copied Agenda" to duplicate the copied agenda to the new workshop. Copy and pasting agendas should be used to quickly set the production of multiple workshops once the first agenda is already set.
- Right-clicking on a workshop agenda and selecting "Register Preset" will transfer the workshop's daily agenda starting at the item that preset registration occurred and transfer the agenda to a preset, which can be applied to another workshop using "Select Preset". For example, if an agenda consists of Isleworks Grilled Clam → Isleworks Baked Pumpkin → Isleworks Boiled Egg and a preset is created from right-clicking the Baked Pumpkin slot, only Isleworks Baked Pumpkin → Isleworks Boiled Egg will be saved as the preset. Up to 10 presets may be saved at once. Players may right-click saved presets to bring up an option to delete them. Presets should be used to save any commonly recurring agendas used for multiple seasons.
Material Allocation
Setting an agenda will allocate a material cost based on the number and types of handicrafts that were set. When a craft commences, the requisite materials will be automatically deducted from the player's island inventory. By selecting "Review Materials" in the top right of the interface, the player can view the current material allocation. If there are insufficient materials for a given agenda, the "deficit" for a material will be a negative number. If there are insufficient materials for when a craft commences, the item will not be crafted and the production time slot will be wasted.
Island Experience
Island EXP is earned after exporting items by talking to the Tactful Taskmaster. One workshop-hour of crafting awards 70 regardless of other factors. If all hourly slots are occupied, a full 24-hour cycle for one workshop awards 1,680 . If all four workshops are fully occupied for a 24-hour cycle, that is equivalent to 6,720 .
Efficiency
By chaining production of Isleworks Handicrafts that share a category, workshops will operate efficiently. For example, if a production agenda has 
Isleworks Grilled Clam immediately followed by 
Isleworks Baked Pumpkin (both categorized under Foodstuffs), then the Baked Pumpkin craft will receive a bonus, producing two items with the time and material cost of only one.
The bonus is only applied if the second item is different from the first, e.g., Isleworks Grilled Clam → Isleworks Grilled Clam will not receive a bonus. However, Isleworks Grilled Clam → Isleworks Baked Pumpkin → Isleworks Grilled Clam will receive an efficiency bonus for both the Baked Pumpkin and the second Isleworks Grilled Clam craft.
Groove
Each workshop will gain one Groove point from commencing an efficient craft. Each Groove point will give a 1% increase in the export value of the handicraft. Groove is an additional bonus for setting efficient workshop agendas.
The maximum Groove available is determined based on the number of Island Landmarks (up to five) the player has constructed: each landmark will increase the cap to 15, 20, 25, 35, and 45.
Supply and Popularity
The export value of each handicraft is influenced by its supply and popularity for a given season. There are several factors that go into determining these, and determining the most efficient workshop agenda considering supply and popularity is fairly complicated. However, because supply and popularity impacts are the same for all players, one must merely consult a crowdsourced agenda recommendation (see External Links) to maximize efficiency.
Supply
Each handicraft is assigned a hidden "supply point" value determining its relative market supply. Items with lower supply will be worth more cowries. The beginning of each weekly season, all handicrafts are reset to 0 supply. Each item is placed in a certain "supply track" that determine on which cycle (day) and how strongly the item will peak in export value. Weak peaking items have "insufficient" supply and strong peaking items have "nonexistent" supply. Supply points are automatically added or removed to the item in days before, during, or after the peak. It is not possible for items to peak on day 1 of a season.
When exporting items, regular crafts will add 1 supply point, while efficient crafts will add 2 points. These points are applied after exporting the items. If one makes too many of the same item, it will cause a supply excess that will lower the item's value in later days, even if the item was initially on a track to peak in value.
Popularity
Handicrafts with higher popularity will be worth more cowries. This changes each season. The "predicted popularity" of a given handicraft is shown in the workshop interface, which indicates the popularity of the item in the next weekly season.
Supply and Popularity Multiplier
Each item receives a multiplier (supply_popularity) to its export value based on its supply and popularity.
| Supply → Popularity ↓ |
 Nonexistent
|
 Insufficient
|
 Sufficient
|
 Surplus
|
 Overflowing
|
|---|---|---|---|---|---|
| Supply Points → | -9 and lower | -8 to -1 | 0 to 7 | 8 to 15 | 16 and higher |
 Very High
|
2.24 | 1.82 | 1.40 | 1.12 | 0.84 |
 High
|
1.92 | 1.56 | 1.20 | 0.96 | 0.72 |
 Average
|
1.60 | 1.30 | 1.00 | 0.80 | 0.60 |
 Low
|
1.28 | 1.04 | 0.80 | 0.64 | 0.48 |
Export Value
The final export value of an item is given by the following formula:
final_value = floor(floor(base_value × (1 + (workshop_rank - 1) / 10) × (1 + groove / 100)) × supply_popularity)
Felicitous Favors
Introduced in patch 6.5, felicitous favors is a system that allows players to earn 
Felicitous Tokens exchangeable for unique rewards by crafting specific items requested by the Felicitous Furball.
Unlock
Felicitous favors are unlocked after the following conditions are met:
- Sanctuary rank 19 or higher
- All 6 production buildings (workshops and granaries) and the Cozy Cabin are renovated to level V
- The final gathering area inside the mountain cave is unlocked through the quest A Subterranean Investigation by speaking to the Determined Digger in the Mountain Hollow area (X:26.7, Y:21.1)
This completes the "An Idyllic Island" vision and unlocks the favors system by speaking to the Felicitous Furball.
Function
Favors provide an alternative goal of the Island Workshop instead of maximizing the number of Seafarer's Cowries. However, it is still possible to create agendas incorporating the requested items that maximizes cowries based on efficiency bonuses, groove, supply, and popularity.
Each season (week) has three different requested items with varying requested quantities. These crafts are unique per player, so following a crowdsourced recommended agenda is more difficult. However, the following are always true:
- There will always be one 4-hour, one 6-hour, and one 8-hour craft, requiring 8, 6, and 8 items, respectively.
- The crafts for the current season will not appear as options in the next season.
- The requested crafts will always be of average demand or higher.
- Completing each craft rewards 10-30 . Completing all 3 crafts rewards 20 . Based on this, players may gain up to 70 in a single week. Up to 150 can be held at once.
Only felicitous tokens earned during the previous and current season can be retrieved. Tokens earned prior to the previous season will be forfeited.
Rewards
10 Felicitous Tokens may be exchanged for one 
Sanctuary Materiel Container at the Horrendous Hoarder (X:12.6, Y:28.3). When used, this item will turn into a random item from a pool. Some items, such as the 
Island Peerifool Whistle, may only be obtained from opening these containers, although they can be sold on the Market Board.
10 may also be exchanged may be exchanged for one 
Vegetal Voucher, of which 200 can be exchanged for an 
Island Adenium Whistle (2,000 total). Because only 70 can be earned per week, it takes a minimum of 29 weeks of Felicitous Favors. However, this mount can also be sold on the Market Board or obtained at a low rate from opening a Sanctuary Materiel Container.
