Now, let's do "Guile's strength". All you have to do is go to the corral on the southwest side of this place (near the Career Trainer) and release the Cold Ones from the corral (the look like dinosaurs). Return to the Beastmaster and complete this quest. You should now be Rank Four.
You can pick up "Covenant of Vitality" from the Career Trainer now. "Pages of Power" is our next quest to complete. Go to the Ruins of Narthain in the west and find four ritual parchment pieces.
There are Narthian Archers here. Kill them if they get in your way, the pages are just that, glowing white pieces of paper on the ground, find four and return to Tirithna. She will give you another quest, "competent scion". This one is farther away, so let's do the other two quests first.
"Use of Allies' wants you to kill Narthian Archers and loot them for their "shinnies". We just saw them when getting the parchments and you might have even killed a few so just go back and slay the rest you need. You will have to find Thamp'zun the goblin to hand in this quest. He is a bit of the way south past the Career Trainer. Follow the road. He is on your right. Now let's do the quest, "Lionbane". Go along the path a bit more south and you will start to see some White Lions. Kill them to get five of their flanks and return to the Beastmaster. He will give you the quest "Mavghann's Challenge". We will do this one since the reward is a weapon. Go to the forests of Lionwalk (where the white lions are). You have to find one of the Silverlake sisters and kill her. She is not far into the forest (on your left) and is in a very tree heavy area with a rock that she will most likely be walking around. You can easily recognize her as the only human in the place and by her shield. Return to Beastmaster to hand in the quest. You should be half way to Level Five now. "Competent scion" is our only quest now, so let's go do that one. Go far past the White Lions until you reach the Mistwood. Kerryn is in the tent. Take the three quests from her: "Hated Kin", "Must Have" and "Legend and Infamy". "Legend and Infamy" is an epic quest meaning that it's very long and can be very hard.
Ularis has the quest "Nimosar's Fall", Telathor has "Dark Ambition", Urathos has "Need to Know" and "Prize of War". Dark Isle Shadows are parked east of Mistwood for the quest "Nimosar's Fall'. Kill five of them. Be careful not to confuse them with any of the other enemies that are in this area or you might be fighting battles you don't want to. Go back to the camp. Rikuld will reward you with some XP. Drop off the quest you just did to Ularis he will give you another quest that you should take. Go far south past the guardians and to Volric on your right (a great Wing Crag Wing will be on a rock near her), talk to her and get the rewards. You will get the next part of this quest. Go back to where you killed the Isle Shadows and go father into the forest to kill Shadow Warriors. Kill eight of them and get their heads. You can kill anyone in this forest and get a head (observing shadow, isle shadows, or dark walkers). When you have eight heads, go back south to Valruc. Click the glowing pikes and you will set the heads on them two at a time. Once you have this completed you will now be Rank Five. You can now go back to the Mistwood to pick up the skill, "Lacerate' from the Career Trainer. You can also do some of the Public Quests or the Scenario Quest if you like.
