Weekly Bosses are battles gotten through special quests that are avaliable again approximately once per week. But you don't have to have the quest to do the battle if you follow someone who does have the quest. Therefore, if you need the items they may drop, you can follow someone else to do the battle. If you have a steady combat partner, and you both need items from the boss, make sure only one has the quest the first time and you can do it a second time directly after.
List of Weekly Bosses Edit
The questrewards for defeating the Boss Battle is always
- Ca100 Hero Seals
- A title specific to the Boss Battle. (The title cannot be traded, so this reward is useless if it's your second or more time to kill the same boss)
