This one is for watching Deathtrap kill 50 enemies. He can get a few kills at the very beginning and will get a lot more later on in the DLC. If you get to the end without receiving the achievement you can go back and farm the Empowered Grawn boss fight and have deathtrap kill the enemies that spawn throughout the fight. This can take a while however as he tends to target the boss, but you hopefully should only need him to get a few more kills at that point. I also covered this in a video guide here.

This one is for getting a live grenade from a slot machine. You can do this at any slot machine, but the easiest way is in Moxxi's bar as she has multiple in close proximity. There is a decent chance to "win" a live grenade so you should get it fairly quickly. I also covered this in a video guide here.

This one is for using a golden key to open the chest on Sanctuary. You can get golden keys from SHIFT codes that Gearbox sends out periodically. There is generally at least one thread on the Borderlands 3 subreddit and one steam guide that compiles all of the existing SHIFT codes if you need one. I also covered this in a video guide here.

This one is for getting a perfect score on Marcus's firing range located underneath his shop. You can do this on either difficulty, but I'd recommend just doing normal. You have to shoot all 15 of the targets before they disappear and before the time runs out so you'll need a gun with a large magazine or at least a very fast reload speed. It can be pretty buggy so it may take a few tries before the targets appear long enough for you to be able to shoot them all. I also covered this in a video guide here.

This one is for getting a loyalty package from all of the weapon manufacturers. This includes Atlas, COV, Dahl, Hyperion, Jakobs, Maliwan, Tediore, Torgue, and Vladof. You’ll need to kill 100 enemies with a gun of each manufacturer. An easy way to keep track of which ones you’ve gotten is just to leave them in your mail and don’t open them until you’ve gotten the achievement. I also covered this in a video guide here.

This one is for completing all six of the proving grounds missions. After you complete "The Great Vault" mission you can get these quests from lodestones on Devil’s Razor, The Splinterlands, Meridian Outskirts, Floodmoor Basin, Jakobs Estate, and Desolation’s Edge. I also covered this in a video guide here.

This one is for completing all 15 crew challenges and all of the side quests in the DLC. The list of side quests and the crew challenge locations are listed below. I also covered this in a video guide here.

Crew Challenges

Skittermaw Basin (2)
Cursehaven (3)
Dustbound Archives (2)
The Cankerwood (3)
Negul Neshai (3)
Heart’s Desire (2)

This one is for activating the talking fish wall decoration 25 times. I’d recommend activating them as you see them during your playthrough of the DLC and opening all fish nets you can as there is a "Talking Fish" decoration drop you can get. Getting this and spamming it is the fastest and easiest way to get the achievement. I also covered this in a video guide here.

Smashing normal piles of Eridium for this acheivement will not progress this acheivement at all.

You must complete all of the mysteries of Ava's podcast side quests to start this acheivement. Once you've completed all of Ava's podcast side quest storyline, you will receive the "Demysteriouslierified" Acheivement along with a legendary artifact equipment called "Mysterious Artifact". You must equip this legendary artifact and destroy sparkly eridum piles to progress to completion.

Additional Notes:
Quest Requirements Notes:

• Ava's Podcast Side Quest's can be obtained on Sanctuary. There are 4 missions in total. You will need to progress through the main story to unlock each mission, with the final mission requiring main story completion.

Tracking Acheivement Progess:

• You can track progress by going to your inventory options, going to your map tab, and going all the way out until you're in the Galaxy overview. Once there, move from fast travel tab to challenges tab. You will need to filter through the various challenge lists to "Filter: Other" (by pressing "Q"on PC or "X" on Xbox). It should start with "Character Challenges" as the fisrt challenge subcategory (for people whose challenges are glitched and overlayed over the filter name). Scroll down this challenge list until you see Director's Cut Challenges Subcategory, and you will see "Might Beyond Sight" as the challenge to track.
• (Full Pathway: Inventory →Map->Galaxy Overview->Challenges->Filter: Other-> Director's Cut Challenge-> Might Beyond Sight)

Eridium Details:

• Sparkly Eridium piles look primarily the same as normal piles except with a sparkly effect to them.

This one is for finding all 18 of the ECHO logs in the DLC. The locations are listed below. I also covered this in a video guide here.

The Lodge (2)
Cursehaven (2)
Dustbound Archives (2)
Skittermaw Basin (2)
The Cankerwood (2)
Negul Neshai (4)
Heart's Desire (4)

This one is for killing an enemy by melee-ing them with a gun that has a blade attachment and melee bonus on its stats. You’ll find plenty of these naturally, but you can also generally buy them from any of Marcus’s gun vending machines. I also covered this in a video guide here.

This one is for getting and unlocking 10 cosmetic items for your character. If you pick up and activate any that you find during normal play you’ll most likely get this one naturally. I also covered this in a video guide here.

This one is for giving Moxxi a tip in her tip jar located in her bar on Sanctuary. You can do either the $100 option or the $1000 option to get the achievement. I also covered this in a video guide here.

This one is for completing 20 of the base game side quests. The list of the side quests for this is below. I also covered this in a video guide here.

This one is for getting 10 vehicle parts from hijacking and scanning enemy vehicles. This can be done pretty quickly by going through Ellie's crew challenges and hijacking random vehicles as you play through the game. I also covered this in a video guide here.

This one is for having purple or orange rarity gear equipped in every slot. You’ll have to complete the story mission “Cold as the grave” in order to do this, and by this point in the game it will be fairly easy to find the equipment to do this with. I also covered this in a video guide here.

This one is for getting all of the vault rewards. It's not technically for completing a specific story mission, but it is required to progress through the story missions. I also covered this in a video guide here.

This one is for winning a duel with a co-op partner. I also covered this in a video guide here.

This one is for buying 20 cosmetic items from Earl at his shop on Sanctuary. I also covered this in a video guide here.

This one is for using a sticky grenade to kill two enemies at the same time. For me this one was somewhat difficult to get as my pet would end up killing enemies that I got low enough for a grenade to kill. So, if you have issues with this one I found a pretty easy spot to do this at a house on the Voracious Canopy map. Just throw one of your sticky grenades through the window and you’ll kill at least two ratch to get the achievement. I also covered this in a video guide here.

This one is for sending an item to another player through the social menu. You have to be in game on one of your characters in order to get this option. I also covered this in a video guide here.
