http://rules.l5r.com/CE_Effects#Continuous_effects "Continuous effects are those found in non-triggered traits, as well as modifier effects that are not triggered (such as stat modifiers on Items or tokens). Example: “Your Samurai have +1F.” Continuous effects from cards upon other cards normally begin when both cards have entered play.
Additionally, if a continuous effect has a condition on it, the effect begins at any point when the condition is met and the relevant cards are in play. Example: "Your Samurai have +1F while they are opposed." In this example, the effect on each Samurai begins when that Samurai becomes opposed.
Continuous effects from cards upon other cards normally end when one (or both) of the two cards leaves play or when the effect's condition is no longer met. In the example, the effect on each Samurai ends when that Samurai is no longer opposed. "
Several lion personalities have a non-triggered trait to gain a force bonus while attacking. "Hagio has +1F while attacking." on Ikoma Hagio is a good example. I assign Hagio to attack, and he gains +1F because he meets the conditions of his trait's continuous effect. My opponent moves him home, causing Hagio to lose his +1F because he is no longer attacking. I move Hagio back in to battle. He is now attacking again, so he meets the conditions of his trait. The rules wiki entry for Ongoing Effects is clear that a conditional ongoing effect is a single effect, regardless of how many times it is reapplied. The entry for conditional continuous effects is not so clear. Is Hagio's trait's +1F while attacking a single effect regardless of how many times it is applied, or does it create separate sub effects each time the condition is met that end when the condition is not met?
