Province Assaulted
Text Limited: Pay 4 Gold: Each player may target and destroy a Personality with a base Gold Cost equal to or less than his controller's stronghold's Gold Production plus 2. Open: If it is not your turn, bow your Stronghold: Straighten one or two target units.
Can I use Province Assaulted in my turn to straighten 2 units? The way the bolded part precedes a comma suggests a condition for the cost to exist. Does this condition refer to the cost or to the effect of the action?

It's a condition for using the ability at all, not a modification of the cost (http://rules.l5r.com/CE_Card_features#Abilities).
