After the recent changes to Belial and Azmodan me and my friends were looking for a faster way to level to 60. Well we used most of the group multiple turn ins but after the patch we found that to get to 60 from 50 was way to slow with 10k quest turn ins over and over.
So after some research on mob xp and using a place we gold farm we decided to give an XP boost set a try.
What is needed is a decently geared 60 that can AOE well and a level 50 toon that can soak up xp like a champ.
To start we need to gear the 50 with xp gear and found that most pieces in the 50 range run between 20 to 24 xp per kill per piece. We were able to get almost 300xp per kill. We also found a helm with xp boost and added a nice Star Ruby for 25% xp boost.
To begin we had the level 60 start with Act 3 Heart of Sin, Hell difficulty. Our level 50 then joined and we entered Arreat Crater Level 1. Doing a speed clear with our geared 60, the level 50 was able to soak up large amounts of xp due to the larger AOE packs. We tried different methods of clearing the whole quest chain but found farming just Crater Level 1 was quicker and more efficient.
On average most mobs gave 2k to 2.5k xp each and elites giving almost 10k. On a good run we could do a full Crater Level 1 clear in around 6 mins with anywhere to 500 to 800k xp. We averaged 5 mil xp an hour with little to no trouble. Of course the better your 60 is geared the faster the clear and my DH is pushing around 40k dps.
