I've got a question about the Force Power Trees and when power upgrades are available. When a power upgrade is connected to two previous power upgrades, do I need to have purchased both of them, or just one?
For instance, the Influence Force Power Tree has the Control Upgrade that lets a player make an Influence Power Check as part of his dice pool. that is connected to a Range Upgrade and a Magnitude Upgrade. Do I need to pick up both the Range and Magnitude Upgrades, or do I only need to pick up one?
In the same vein, the Move Force Power Tree has the Control Upgrade which lets you Force Hurl an object. That has two Range Upgrades that lead to it. Do I need to purchase both Range Upgrades or just one?
According to the rules as written, it would seem like you only need one, but I know I've heard somewhere that both upgrades needed to be purchased, so I'm not sure if there's a rule I've overlooked.
