Hey,
as you all know, probably all easy resplendent chest farm spots are nerfed, so we are left to farm regularly.
Sooo here is a guide I made. Found this way the most efficient as for item farming because it is focused on chest farming with elites and valor stacks on its way.
1. Choose quest Siegebreaker - Kill siegebreaker
2. Go to Rakkis Crossing waypoint to get Tyrael as extra companion
3. Back to Bastion's Keep Stronghold and run out over Arreat Gate
4. At the end of Arreat Gate go into Fortified Bunker - large dungeon, easy mobs, everything is meelee, just watch out for flies - Resplendent chest usually lies in level 2
5. Use dungeon portal to get out, go into Battlefields and look in lower part of map for dungeon, usually around ruins of towers and stuff
6. There are 2 dungeon options, Foundry - rather large dungeon with soul rippers! I wouldn't reccomend going there
or Forward Barracks - small dungeon with chance for Resplendent chest
7. Port to town, go to Bridge of Korsikk waypoint - Fields of Slaughter
8. Here you have to do a bit of running and search for caves, both are medium size
9. If you find Caverns of frost - they are full of lacuni and other annoying stuff, wouldn't reccomend it,
but if you find Icefall Caves - they are full of bulls which get stuck in narrow paths, easy killable frogs etc. and 100% Resplendent chest in lvl 2
10. Port to town, go to Rakkis crossing waypoint and head forward to Edge of Abyss
11. You may find Underbridge near Edge of Abyss on your left, it got nerfed but it is small dungeon with chance of Resplendent chest
12. Get out, go to Edge of Abyss, kill Siegebreaker
Identify everything, hope for some good stuff
Hope this will help anyone, I'm currently doing this and it seems worth, you will have 5 stacks of valor buff after 1st dungeon.
Cya, Asgorath
