The Tribute Camp is where the nations of the desert, Harad and Rhun, come to offer their tribute of resources in addition to the one provided with their blood in the form of Mumakil, Easterlings, Haradrim Lancers and Rhun Halberdier Warriors. This provides Mordor with the necessary resources to fight on and plunge the world in darkness. As per most resource buildings they can be upgraded twice with either the Pantry upgrade, the Resources upgrade or the Defensive Measures upgrade.
Forged Tools: Upgrades the building to rank 2. At rank 2, economy buildings produce 25% more resources and gain 750 additional hit points.
Forged Worker's Tools: Upgrades the building to rank 3. At rank 3, internal economy buildings produce 20% more resources and gain 1500 additional hit points.
'The upgrades can be researched by casting Sauron's Influence of Sauron'
Note: Mordor does not research economy upgrades, instead it relies on Sauron's level 3 ability Influence of Sauron. When cast upon an economy structure it will level up all economy structures of that type (internal or external). In order for economy structures to reach level 3, Influence of Sauron must be cast on both of the structures of that type. E.g: For the Tribute Camp to reach level 3, Influence of Sauron must be cast both on the Tribute Camp and on the Arsenal as they are both internal economy buildings.
Influence of Sauron - Sauron fills a building of Mordor (excluding Tol-In-Gaurhoth and the citadel) with his will, unlocking specific effects like new units or upgrades. All internal resource buildings gain a level
- 5 economy structures or less: 100% production
- 10 economy structures: 75% production
- 15 economy structures: 63% production
- 20 economy structures: 54% production
- 30 economy structures: 44% production
- 37 economy structures or more: 37% production
Tributes from the East - The Tribute Camp generates resources and provides a reduction to the cool-down time of spellbook spells up to 25%:
- 2 Tribute camps: 5%
- 3 Tribute camps: 10%
- 4 Tribute camps: 15%
- 5 Tribute camps: 20%
- 6 or more Tribute camps: 25%
Having many Tribute Camps will allow spellbook powers to cool down faster, essentially allowing you to use them more often, summoning more troops at an incredible speed (especially considering that having 6 of these means a whole quarter of the reload time is taken out).
