As suggested by Nabiki (suggestions), could it be possible to add some quests?
"If it's possible can create a quest "Dancing with Ogres" killing ogres to get ogre belt killing 500~1000 or blood "Drinking with Ogres" for 250~500."
I would call the first quest "Shreeeekcide!!!" though
Also, Would it be possible that if someone of the party gets the kill, everyone gets the check of the kill if any quest active? As like with the pets.
