Respawn Bosses is an obtainable option to respawn all bosses in the server of the player that bought it, with the exception of Raid Boss. This product is mainly used to grind mastery on fruits, swords, guns and fighting styles.
Obtainment[]
The player can buy them for 
50 each in the shop, or by having another player gift it to them.
Notes[]
- This only applies to regular bosses, hence it wont respawn Raid Bosses.
- A cheaper alternative to this is server hopping which, although is not guaranteed to have a boss every time, is still reliable.
