I couldn’t find anything about this on Wowhead or the professions forum so casting a wide net here hoping someone might know.
The new max skill engineering goggles once they have their traits filled in give a total of +75 to Engy skill for a max of 250. Prior to 8.2 there was a similar, smaller bonus on the old skill 150 goggles that let you scavenge certain robots in Motherlode. I was wondering what needs 250 skill to scavenge. Stuff in the Mechagon dungeon? I haven’t taken my Eng in there yet.
