Patch 1.8 can't stop me that easily. The lack of Dupe Glitch is definitely more rough for Heroic, but the discovery of Instakill Glitch makes up for it.
I also decided to include some fishing in this route, since getting Black Marks is much harder when we skip most bosses lmao. AND killing the Angler Trickster is muuuuch more difficult than on Story mode. Got really lucky with the fishing segment, getting an Epic catch early which allowed me to skip a lot of fishing. The run was not good by any means though. Getting Serrated Dirk was awful, I died like 3 times to the Treasure Golem. Same with Maokai, died at least twice before getting a half decent fight. And that's all the bosses we kill "normally", everything else we handle with Instakill Glitch (as long as it works. Most bosses I had to try it twice...)
