How do you build on a Grovetender Outpost source well when you already have six spires in play?

Question

Accepted Answer

Build along a chain of earthscapes so each spire gives influence to the next, removing earlier spires as needed to stay under the six-spire limit. Other routes are a unit that builds without influence, an extra earthscape that shortens the path, or a landmark that rewards a spire.
