JMS Big Bang Tespia Open For All (?)

Also, do you know what publicReward and explosiveReward are?

Explosive Reward means the Boss type of reward, where the items "explode" from inside the monster, like papulatus, and not alike normal monsters where the item just spins off them.
Public Reward means it's not based on the one who dealt more damage to the monster, and that even a leecher can loot the item if no one does.
