I’m sorry because this has been answered before, but many players continue to disagree with the ruling on grounds of rules as written and some clarification would be helpful.
Yoda’s card states that: “After another friendly ship at range 0-3 spends 1 or
more <force>, you may spend 1
<force>. If you do, that ship
recovers 1 <force>.”
The rules reference says: “While it performs an attack, a ship can spend any number of <force> during the Attack Dice step to change that number of its <force> results to <force> results. While it defends, a ship can spend any number of <force> during the Defense Dice step to change that number of its <force> results to <force> results.”
Many players (and TOs) read this to mean that Yoda can let that ship recover just one force per opportunity by spending just one force. Then the idea is that ‘any number’ in the RR means that each modify dice step is an opportunity and that ‘any number’ of force charges spent would be one opportunity. Based on his card text and this reading of the RR that seems at first glance right doesn’t it? And this is the source of disagreement.
Previous rulings by Dee and Kris however have taken a different view and consider each force charge spent to be an opportunity. By these currently active rulings Yoda can spend a force to let the other ship regain a force each time a force charge is spent, and therefore potentially multiple times within each modify dice step.
Unfortunately there is such disagreement on this that the rule is in effect disputed and hard to apply, and it would help very much to clarify the reasoning.
