I have been testing different runs and the most efficient groups of elites to kill for the highest drop rate of rares in inferno act 1, and this is what I have come up with.
I stick to this run like Velcro because it is so consistent with the rare and blue mob spawns.
Waypoint 1 -
Northern Highlands -> run west to the border and north and south… look for the watch tower. If the watchtower doesn’t spawn, remake the game. If it doesn’t spawn elites, remake the game (sometimes it glitches out). There’s 2-5 packs here. TP after clearing the watchtower.
Waypoint 2 -
Cathedral Gardens Level 3 -> always an elite pack here. You sometime have to run backwards. TP after killing him.
Waypoint 3 -
Cemetery -> clear the first elite out of every dungeon. JUST THE FIRST. After the first one, TP back and take the way-point again… it’s not worth looking for a non-guaranteed elite.
Waypoint 4 -
Leoric’s Manor -> run backwards, there’s a 25% or so chance there’s an elite IN the manor, but there’s a guaranteed elite in Leoric’s Manor Courtyard.
Waypoint 5 -
Festering Woods -> guaranteed 1 outside, and 2 more guaranteed in each of the two dungeons, and there’s a chance for the king of the hill event to spawn 1.
Then you can do the Warden / Butcher if you want ( I would )
