Green Guardians Rule Book

Tree of Knowledge
The Tree of Knowledge is where you mark your
progress toward learning Breakthroughs that provide
special abilities and Prosperity Points. There are
three levels on the Tree of Knowledge: Resilience,
Knowledge, and Breakthroughs, where Resilience
and Knowledge are prerequisites to Breakthroughs.
LEARN RESILIENCE
Cost: 3 resources of that Resilience type
(ie. learn stabilization = 3 x earth).
Benefit: you may invest 1 resource to overcome a
disaster of that same type.
(ie. Rid 1 earth disaster = 1 x earth).
LEARN KNOWLEDGE
Cost: 3 resources of a kind or 3 different resources,
or 1 Research, provided all prerequisites have been
researched.
Benefit: Knowledge is a prerequisite for other
Knowledge and Breakthroughs. The more Knowledge
required, the more Prosperity Points the Breakthrough
is worth.
LEARN BRAKETHROUGH
Cost: 3 resources of a kind or 3 different resources,
or 1 Research, provided all prerequisites have been
researched.
Benefit: Breakthroughs provide Prosperity Points
based on the amount of Knowledge/Resilience
required. Breakthroughs give you special abilities
(see Brakethroughs and Abilities, pg. 16).
Once a research token is applied to the Tree of
Knowledge, you cannot undo or move the Research
token once played. Resilience and Knowledge can
be learned by more than one Guardian. BUT
Breakthroughs can only be learned by one Guardian,
after they have learned all of its prerequisite
Resilience and Knowledge. Breakthroughs earn you
special abilities and Prosperity Points as described on
the respective card.
Example, learn Potable Reuse:
Potable Reuse gives you 4PP. Hence, there are
4 prerequisites.
To gain the Brakethrough "Potable Reuse" you have to
buy all the prerequisite Knowledge and Resilience, as
well as the Brakethrough itself:
• Waste Collection cost: 3 x Animal
• Irrigation cost: 3 x Water
• Treatment cost: 1 Research, or 3 x same resource,
or 3 different resources.
• Biodegradation cost: 1 Research, or 3 x same
resource, or 3 different resources.
• Potable Reuse: 1 Research, or 3 x same resource,
or 3 different Resources.
