Great works

A great work, with a feature

Great works, also called wonders of the world, are special holdings that are constructed at great cost and confer lasting benefits. Great works bring new ways to spend a dynasty's amassed fortune by creating new developments that can provide bonuses for the character, its family, and the realm.

Contents

Building a great work[edit]

Great works can be built in any province by clicking the "View great work construction" button on the province menu. From there, the player has to select from a set of available great work options. Once the first level has been completed it is possible to upgrade up to level 4 with additional features suitable for said great work. Each stage grants 2 feature slots, which allow the ruler to customize the benefits of their great work, up to 8 slots at the maximum level.

Great works have a base construction cost and a monthly construction cost. Both of these costs increase with the number of (active) great works already existing within the realm: 40% more gold per great work, and an additional 80% increase for each great work of the same type. Thus it is best to focus on upgrading one great work to stage 4 at a time, and to build a variety of great works instead of the same one multiple times.

Both stage construction and feature construction can be paused by the ruler, in case they cannot afford the monthly cost of continuing construction.

The cost of great works can be reduced by Construction technology and by having the Architect trait.

When building your first great work, the "Build a Great Work" Ambition will add a bonus feature (if it is constructed in your demesne).

Looting and Restoration[edit]

If the current owner of a Great Work has not participated in building or restoring it may loot it for gold. Looting a great work grants 300, 500, or 800 gold, depending on how expensive the Great Work is. Looting damages it, dropping its current stage level by one and rendering it non-functional until it is restored. Looting a great work takes a period of time that varies per great work.

Looted great works may be restored to their former glory, and must be restored before the current owner may regain its benefits and begin upgrading it again. Similar to building a great work stage, restoring one has an initial cost and monthly cost. A ruler that looted a great work may not participate in its restoration.

Events and Decisions[edit]

Events and decisions common to multiple Great Works and features.

Intimidating Great Work features add a targeted character decision, Try to Intimidate, to the right click on character menu, with a 2 year cooldown. Higher diplomacy and a craven target raise the chance of success. Only usable within the same realm.

The decision gives the following options:

  • Gain +20 opinion with the target for 2 years on success, lose -25 opinion for 2 years on failure
  • Gain a favor with the target on success, loss -25 opinion for 2 years on failure
  • Gain +5 opinion with the target for 2 years on success, lose -15 opinion for 2 years on failure (higher chance of success than the first option)

Private Conversation[edit]

Secluded Great Works features add a targeted character decision, Private Conversation, to the right click on character menu.

Burial Ceremony[edit]

Great Works considered Burial Grounds wlll trigger an event on ruler death for a burial ceremony. The options are:

  • Expensive Ceremony: Lose between -100 and -400 gold, gain +150 prestige and +50 piety. Characters who liked the dead ruler (+20 opinion or higher) gain +15 opinion of you. Characters who hated the dead ruler (-50 opinion or lower) lose -15 opinion with you.

2 200 0

  • Magnum Opus on Stellar Astrology (Quality 1)
  • Magnum Opus on Planetary Astrology (Quality 1)
  • Court Etiquette - Volume 1

A Town Is Born[edit]

An event that fires 50 days after a Great Work feature's completion that grants a holding slot to the Great Work's province. The trigger conditions are:

  • At Peace
  • Great Work is at least 50 years old (Stage 1 onwards needs to be 50 years old, does not required completed work)
  • Great Work has at least 2 features
  • Event has not triggered before on the province

Be sure to pause your feature's construction so that it finishes while you are at peace if you want this event to fire. This has a 9% chance to fire each time a feature is complete and the 50 days are up

Crumbling Masterwork[edit]

A yearly pulse event that requires a Great Work that is at least 100 years old. Two options:

  • Repair the work. Lose -50 gold, gain +40 prestige.
  • Sell the pieces. Gain +100 gold.

This event does not cause damage (requiring restoration or losing a stage like looting) to the wonder.

Send Alcoholic Gift[edit]

The Brewery and Vineyard features enable a targeted decision to gift alcohol to any character within diplomatic range. +10 opinion for 1 year, with a 1 year cooldown.
