The changes were supposed to be 1-25 charm drops, less HP and shadow step. Was any of that implemented?
Shadow (Epic 3.5 Boss) will be changing to a bigger event now. His original spawn location will be a random location, and throughout the battle, he might shadow step on players. When he does this, he'll forget about you, so he won't run across the zone and train or anything. You'll just need to go find him again. Think of it as a Black Reaver event slightly modified. I'll be adding charm upgrades (1-25) on him as well to make the efforts worth it. If he Shadow Steps, then next guild to reach his new location gains rights to him. Guild Instances are suggested to prevent other guilds from stealing him. Trying to think up a custom item that would be worth putting in his loot list in addition to the Epic 3.5 book and a charm upgrade.
