I got Eldrig the Old this weekend too :D . Just got done killing Trakanon and they asked me what pieces I needed next (these were RL friends and a wizard that we know on the game). I told them piece from Eldrig the Old and Nezekezena, so the wizard teleported there. I told them that it could basically be any mob in the zone for a ph and where it wanders between. So the 65 magician summoned his pet, two blades of kedge, and one of the haste belts. The enchanter dire charmed the highest thing that he could do and buffed it up. And the two wizards... well, they nuked stuff :lol . So needless to say, they were slaughtering everything they saw (this was 4:00 AM in the morning, so no one was in the zone but us). After about 10 minutes, they told me to go check the spawn and see if I got it, I waited a minute and something spawned at (I think it was 500, -4000). The wizard we knew on the game was going to go do something else, so the other wizard told us to go check Nezekezena while he killed anything that appeared. 5 spawns later, Eldrig the Old spawned (the magician and enchanter were done killing Nezekezena and were already back). Then I was ready to go do the turn-ins :D .
Anyways, thank you for the WONDERFUL guide on how to get the Bard epic Kocho :)
