Justly Earned Victory
Battle: Target your Personality: Move a target enemy Personality with lower Force or with fewer attachments home.
Battle: Negate all current Force bonuses and penalties to cards at this battlefield from actions.
Question is about second battle action: Does it negate a penalities or bonuses from terrains (ex. Doomed Undertaking) and recons (ex.Daidoji Reita) or negation applies once and then penalities and bonuses comes again as countinous effects?
Justly Earned Victory's second Battle action's effect negates all current Force bonuses and penalties to cards at the current battlefield from actions. This is an instantaneous negation. As a consequence, when it applies to ongoing effects such as Doomed Undertaking's Terrain action or Daidoji Reita's Recon action, they have their duration end immediately and they do not reassert themselves later.
Duration and scope of negation effects: If a type of ongoing or continuous occurrence is being negated (for example, when Force bonuses are negated), then: All current ongoing occurrences of that type have their duration end immediately.
Moreover, usually such Terrain or Recon effects lasts “while” the card they affect are at the current battlefield. If such a card is there when Justly Earned Victory is played, then its unit moves elsewhere and goes back there, these effects remains negated.
Ongoing effects: An ongoing effect that is applied “while” some condition is true ends when that condition is no longer true, and takes effect again if the condition becomes true within the stated duration of the effect. Nevertheless, a conditional ongoing effect is a single effect, regardless of how many times it is reapplied or takes effect anew. If it is negated, it remains negated if the effect is reapplied due to the condition being met anew.
