Orge quests are so vague it's frustrating! I just did this quest last night. Sheeesh, sometimes I just hate quests! Well, anyways.... here is a walkthru, I hope it helps to save other peeps sanity.
The walk thrus here on Alla and other sites did help me, but, at the same time, lead me astray! :(
----------------------------
Quest: Ogre Warrior Level 15
Starting NPC: Warlord Brogar
Starting Area: Oggok
*Note; all mobs to be killed are yellow to level 15.
1) Talk to Warlord Brogar. He tells you kill a Burdened Mog Thug, who stole some supplies.
2) Go out of Oggok north gate run north, you'll find a temple ruin occupied by Orc Thugs. From there, run west just a small way. The area that he spawns in is Sphinx Pryamid (s). Mog Thug does not spawn on the road; he spawns just off the road on the north side. Kill Mog Thug and loot supplies.
3 Now take supplies to Provisioner Mogdunk, he is located by the merchant who sells warriors their spell scrolls. He sends you to take the supplies to Provisioner Oomgig in Kerplunk (C). Now you need to run coach for Kerplunk, try to get invisi and sow, the mobs around Kerplunk are too red and too many for a level 15 to sneak past. Sign ledger for coach.
4) Ok, now Provisioner Oomgig says he needs a Bundle Of Spears, to obtain these find and kill a Tae Ew Weaponsmith. Run to West Ferrott (C), or West Ferrott (W). I found him in the (W) section, other sources says (C). As all these towers look the same, here is a description of the one I found him at (W). The tower had at least one road going to the tower mound, at the entrance to the tower mound; there are two poles, one pole on ether side of the road. The weaponsmith spawn location is something like a tent area, but different. Also, this spawn spot is right next to the two poles at the mound entrance. If there is a soldier as a placeholder, kill him, and keep on killing them till the weaponsmith spawns. Loot Bundle Of Spears and take them back to Oomgig in Kerplunk.
5) Oomgig says you need to kill Weary Troll Raider loot what he drops, it a no trade item, I forgot the name of it. There are three Troll Raiders on top a tall hill right next (West) to Kerplunk. If you pull very carefully, you can pull just one from the others. Beware; there are a lot red mobs on this hill too! Loot what they drop, return to Oomgig.
6) Return to Mogdunk, and then to Warlord Brogar to end quest.
