Vanquish

Description
To vanquish an explorable area is to kill every aggressive creature in that area while in Hard Mode. This can include mobs that do not show up in the radar.

Players earn an extra 5 XP and 3 gold per enemy defeated after they finish vanquishing an area.
 * Example: If a player needs to kill 200 foes to vanquish an area, this results in that character getting an additional 1000 XP and 600 gold when completed (exact number depends on total kills).
