The Wishing Wall has some interesting buffs and bonuses that it can grant. One of which is to skip the first boss, via “The Fourth Wish”. This takes you to a location after the first boss where you can then backtrack to get the loot from the first raid loot chest:
Unfortunately, it scales the loot to your current power level, so if you’re not raid-powered, it will still only give you items that are at most a moderate power increase. I’m currently max power of 518 and I got a 511 Hood of the Great Hunt just now on my Warlock.
