Defeating giant black wolves
Get ready to use the smash skill. Use it on the wolf, then just keep hitting it. When it is halfway down, quickly get a bow and shoot from a distance. Then, finish it off. Note: This works better if you have two swords equipped.
Golem and metal skeletons
Start by luring the golem into another room, then kill it. Then lure the metal skeletons one at a time into a room and ambush them like the golem. You can lure by hitting them, then running to where they will be ambushed. You can also lure them away to let other people heal.
