A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing.

A player, 6 August 2007
An ability may be used when its designator indicates:
* At an opportunity to act in the ability’s player’s Action Phase if it is Limited; * At an opportunity to act in any player’s Action Phase if it is Open; * At an opportunity to act in the Combat Segment if it is Battle; * At its specific trigger if it is a Reaction.
Does the current ruling mean this has been altered to designate when you can not play actions?

Working on it.
