Who: Fergarin Bardon I, -767, -772, -20
Req to request: Ally to Wraithguard Leadership, Fergarin's 3 tasks, Kangur
Req to join: none
Key: "information"
Raid size: 54
With evidence in hand, Fergarin sends you off to get Udengar. He is going to be speaking at the pulpit, with several followers in attendence. Your task is to sway the followers you can, then take Udengar down.
Make sure NOBODY zones in until the raid is ready to go, as a timer begins the moment someone does. When you zone in, invis up and head out of the intital room. As a raid, begin moving north, picking off see-invis along the way. Make your way to the statue of Rallos Zek (see map below, red line). Udengar will begin giving a speech. While he is doing so, clear the area and pull in the red con guards that are standing outside the pulpit. If you /say "evidence of treason", the guards will stop and demand this evidence. Give them a letter from the Kangur raid, and they will either continue attacking, deagro and go away, or even join your side. Their reactions are generally tied to the name of the mob, but not 100% consistant. In any case, after all the guards have been dealt with, wait for the speech to end.
Once he concludes, the mobs in the ampitheater leave. Make sure you are up at the statue to avoid agro'ing the throng of giants. After the rest leave, Udengar and his two bodyguards walk out and begin heading NE. Wait until he has gotten a bit away (around the Green spot on map), then agro. Udengar then becomes rooted with an aura knockback while the 2 guards charge. Bring the guards into the ampitheater, kite one, and begin beating down the other. Do NOT try to slow the guards. If they are slowed, it reverse and instead hastes them making them significantly harder. Once the first dies, beat down the second. When the second dies, Udengar becomes unrooted and charges the raid. Just like the guards, do NOT slow Undegar or it he gets insanely powered up and AE ramps constantly.
When Udengar charges, about a dozen hammers spawn. They come in two types, "a hammer of zek" which are mezzable, and "an unswerving hammer of zek" which are not. When killed, more hammers respawn, so instead kill the unswerving until only mezzables remain and lock them down. Meanwhile pin Udengar in the hall leading to ampitheater and begin beating him down. He has AE rampage and can only be cast on from melee range, making life hell on casters. He has a short range AE, Apathy of Zek which increases melee damage taken. It is unresistable, with 8 corrution counters, and recast every 30 sec or so. Main tank should get a constant stream of corruption cures, but likely not worth trying to cure the entire raid.
At 50%, one of the guards respawns. Kite it around while taking Udengar down. Once dead, bring the guard in and kill him too.
Udengar has a 4 day lockout. He drops 1-2 runes and 3 items from the following list:
