In the image above you'll see a red circle and the markers for my party. The skeletons will ambush you in the circle if you come from the beach, if you come from behind them you'll get the drop on them.
The enemies are
- two archers
- two swashbucklers (2-handed)
Killing all four will grant you 800 Experience.
If you happen to come from the beach keep three of the party members back where you see my icons and use one character to engage and pull them into the choke point, once their down in there you will have an advantage against them.
