When a Vehicle or Droid Trooper unit suffers 1 or more Wounds from an attack that has the Ion X keyword in the Attack Pool, after the attack is resolved, it gains X Ion tokens.When a unit starts its Activation with 1 or more Ion tokens, roll 1 white defense die for each Ion token it has. If any Blank results are rolled, that unit makes 1 fewer action during that Activation. At the end of a unit’s Activation, it removes any Ion tokens that it has.If an Attack Pool includes the Ion X keyword, at the start of the Modify Attack Dice step, before resolving other effects the defending unit must flip up to X active Shield tokens, if able, for each
or
result in the attack roll.
