Belial and Azmodan stage on the Uldyssian Path: only one Belial is labeled "Uldyssian's Memory", all the fake ones are just called Belial.
Also, cutting the xp gain on so many items to 1%, what's even the point of having it? A friend of mine just upgraded his laz charm and it gives 1% xp gain, 1 skill, and 10 attributes for the amount of farming needed to get all 6 emblems. I guess this is another mistake because the patch notes said 5% xp replaced the max skill.
Overall, the only way to reliably get xp gain is crafted jewels, which with the xp gain nerf rendering another item useless with that deckard cain staff besides some Lem Jewels, wouldn't it be best to j ust remove the stat at this point? You're already getting something like 5-15 xp per kill at higher levels, if that, in farming areas (and thats already with the xp gain from the khalimgrad and death projector charms which have noticeable values at a total of 25%).
