El Search Party Collection
El Party Collection is a new feature introduced in the Korean server in the 6/18 update.
Details
To unlock the system, you have to complete a quest from Camilla after reaching Level 99. (Details to be revealed)
After unlocking, you have to activate a line of each character, which can be done by leveling the corresponding character. For example, creating an Elesis, then job-changing her to Grand Master will activate the collection.
The collection can be upgraded, depending on the job. You can upgrade to level 2 effect by advancing the character to 3rd Job, and level 3 by activating Master Class on it.
Stat bonus won't stack with each others (for example, if the player has Elesis in her Master Class 1st job path, then only the level 3 effect will be applied). However if a different character with the same effect (such as Rage Hearts having same effect as Empire Sword) is activated, it will stack.
