Expedition Bonus

"Expedition bonus is basically a 'how brave for you to come so far from town and hunt monsters' bonus. Usually, if you hunt outside of town you'll receive 300%, and 400% if you go further out. Even monsters with the same EXP will give you different EXP depending on the Expedition bonus. You might as well hunt further away from town." -Taken From "How to Enjoy Field Hunting"

The truth is you really don't have to be that far from town to receive a pretty hefty bonus. You can receive a 300% in the area just south of Tir Chonaill (area's 2 and 3 on the map) where gray and white wolves spawn. You can also get a 400% bonus in the area east of the grasslands (around area 6 on the map) at the boundary between red fox and black wolf spawns.

Although used as revival points, land marks in Iria are not considered "towns", so expedition bonus will be at 400% when near a mark.

• For more clarification, expedition bonus is determined by distance from the last town/landmark you visited before your last logout/channel change. For example, changing channels in Qilla Base Camp and travelling to Long Horn Gnus will give an expedition bonus of 400%, but if you change channels there after visiting the Flower Mark, expedition bonus will be based on distance from the Mark instead.
