If you're too far away, they'll throw pieces of wood at you, and arrows don't work well. Instead, go up and use your fierce attack (Tri) and back up out of his club reach. Repeat this using your fierce attack once (or twice if your fast enough) until both are dead. Also, don't worry about the second troll until you've killed the first. The first one will be blocking it's path and it won't break through all three wooden logs. And if you do run low on health, there's a container thing with health to the right after you go through the arch. This level is kinda nuetral so any character works fine. Any way, here ya go.
