Most efficient way to fast farm Halloween Event (25 Hecktoplasm+Heck map)

Saw many youtube videos suggesting you should farm in Athens or other slow maps, actually this is fastest way, any trial map will work though, and in Heck just go for the “key” mobs that unlock entrance to next level, the other mobs are useless to kill/loot unless you see a yellow skull, do not rush the boss pylons they bug very easy, wait for all 3 to spawn before shooting first one, I failed many fast runs bec of this stupid bug, here you go full event in 10 mins give or take, True Vault Hunter Mode Mayhem 3
