If this ruling, based on the rules change, for Whispers of the Dying Sun is going to be enforced can we please get the second paragraph under "Additional Use" in the glossary changed? I am finding it difficult to reconcile it with the third paragraph. Obviously a "Once per X ability" doesn't need an explicit rule to allow it to be taken in a smaller window of time encapsulated by it's original restriction? Specifically, the underlined sections use of "once during the battle" with a reference to a wider time restriction implies it was used outside the current battle. Changing "once" to "twice" would clarify this, and make it mesh much better with that Third paragraph, and hopefully avoid future questions of this nature (assuming the rule/ruling isn't reversed again)
Some effects grant an additional time an ability or trait can be used in a period of time (for example, “an additional time per turn”).
This additional time also applies to any period of time greater than the one granted. Example: An ability that can be used "one additional time this battle" can also be used once during the battle even if it was restricted to once per turn or once per game.
The stated period of time also means the original ability's first use must be taken within that period in order to gain an additional use. Example: A "once per game" effect can be used "one additional time this turn." The player must take the use with the "once per game" limitation during this turn, otherwise he gains no additional use.
Some effects grant a "second" time an ability or trait can be used. "Second" is equivalent to "additional" in all ways except that there is only one "second" time per period of time, whereas there may be any number of additional times.
