As Duroon explained...A passive is just what the word means (Passive). It's always in use and can't be placed on hotbars as they have no use there anyways. :)
The following effects have been added when the winning side has the Seal of Strife.
CP Gauge Change
* When owned by Dawn: A CP gauge of a player who belongs to the Dawn side increases by 10%, and the CP gauge of a player who belongs to the Dusk side decreases by 10%.
* When owned by Dusk: A CP gauge of a player who belongs to the Dusk side increases by 10%, and the CP gauge of a player who belongs to the Dawn side decreases by 10%.
* When Strife is not owned: Same as before (no changes incurred).
Returning to Town in a Siege
* When owned by Dawn: Same as before (no changes are incurred); player restarts in the second nearest village.
* When owned by Dusk: A clan that has participated in a siege restarts from the first town at the time of escape and death.
* When Strife is not owned: A clan who has participated in a siege restarts in the first town at the time of escape or death.
no offence but do we really need more incentive not to fight for the seals?
It adds more reasons to fight them, aka if you want to take a castle, the best way to deal with it, go dusk and win strife, or remove strife from dawn if they have it.
Biggest strategic advantage is, you get catas more or less for yourself :P
There's lots of strategic advantage here and I bet more will come in the future.
