Ok, since no one seems to know about the OT hammer and eigther the site is down or alla doesn't know much about it here's how you get a free gate item you can use as many times as you want.
For this you need kindly (or maybe better) faction which is some screwed up name but con the cliff golems in the "overthere" to find out. There is only one way to get this faction up and it takes ALOT of turn ins but at least the mobs are easy to spot and easy to kill.
Step 1. seek and destroy
Your first mission is to eliminate any sarnak BERZERKERS you can find. The item of interest is the sarnak war braid these creatures at times posses which you will be able to spot a zone away as a chicken/reptile thingy holding a whip. Collect an ungodly amount of these and report back.
Good job now you're ready for opperation "Get behind the Darky". For this next step you'll need to bug a shaman until he /ignores you or makes you a dark elf potion if you con ready to attack to the cliff golems. Doing so will make you apprenesive to captain rottgrime and all the other Kommies in the enemy encampment. Find this captain the drop off, now he may try to bribe you with goods and uber loots simply laugh in his face as you destroy his sad attemp. After tricking the enemy into regarding you amoungst there own it's time for your final task.
Finally the fruits of your labor are within grasp. Find an operative we've placed inside the camp for your reward. Seek out an undead foreman who will ask you for 2 jade for confirmation of the job completed he in return will hand you a hammer that will port you to him incase you recieve anymore intelligence. This is your mission, you will complete it because I have trained you well. good luck soldier.
