Does anyone happen to know if player abilities granted by cards like I am Ready count as an ability with a card title to fulfill the Ring of Water's play requirement?
Clarification on Ring of Water Play Requirements
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. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.
When determining whether targeting, costs, effects or actions come “from” or are done "by" a card, look to the card where the thing in question is originally physically printed. If it is printed in the rulebook then the effect is not from any card. Example: Your event card gives another player an ability. The action from that ability, and its effects, are “from” your cards even though they are “on” the other player.
You can read more about where effects are "from" here.
Now, if an effect grants an ability to, say, one of your Personalities then the ability is "from" that card.
Something like The Way of the Horse and Bow:
Limited: Target a Samurai Personality you control. Permanently give him the Cavalry trait and "Battle: Bow this Personality: Produce a ranged attack with a strength equal to this Personality's Chi." Draw a card.
Could give your Personality an ability which you could then use in Battle and that would be an Ability from a card with the Personality's card title due to this:
EXCEPTION 3: Effects of traits and abilities given to other cards, copied from other cards, or on created cards, come from the card they are currently on.
