How to Farm Destiny 2’s Dares of Eternity For New Craftable Weapons

The very first thing you should do before doing any runs of Dares of Eternity is stop by Xur’s Treasure Hoard and load up on bounties. While Xur’s bounties do not provide any extra loot or reputation with him, they do provide XP which is important to acquire in order to progress this season’s Battle Pass. Might as well get them done at the same time as your runs!

This is the most important step to farming craftable weapons. In order to be able to make them, you need to earn five Red Border weapons per craftable weapon, which are rarer than normal drops. This means optimizing how and where you spend your Strange Coins with the Starhorse to get as many weapons as possible.

First and foremost, the Starhorse sells six bounties, each one costing Strange Coins, and rewarding Strange Coins as well as Paraversal Hauls. Five of them change daily, while the final changes weekly. You can hold only one at a time, so in order to complete them all you must do at least six runs, returning to the Treasure Hoard after each completion.

Paraversal Hauls are lootboxes you can buy from the Starhorse, which reward exotic and legendary gear, strange coins, and most importantly Treasure Keys. These keys are what give you the best chance to get the Red Border weapons you will need, so it is important to get as many as possible.

While you can buy a treasure key directly, they are more expensive than Paraversal Hauls and do not give any Strange Coins in return. Since Paraversal Hauls are cheaper, reward most of the Strange Coins you spend back, and frequently drop Treasure Keys, they ultimately wind up being a much more efficient method. Additionally, they give extra loot that isn’t available anywhere else!

Completing Dares of Eternity on Legend difficulty for the first time after the weekly reset guarantees you exactly one red border weapon. While it isn’t much, it is a good start and helps provide players with a direct and deterministic way to pursue these weapons. While Legend is harder than normal, and contains champions, it is still a walk in the park for any fireteam that remembers to put champion mods on.

The boss doesn’t change randomly either, rather changing from week to week, so looking it up ahead of time means you can guarantee yourself infinite heavy ammo at the end as well! Additionally, Legend runs of Dares have a higher chance of dropping Red Border weapons over normal even after you do your first run.

Unfortunately, the player inventory can only hold a finite amount of Strange Coins and Treasure Keys, meaning it is important to keep track of how many you have in your inventory to optimize how many you can get. Once your inventory is full, and they start being deposited in the Postmaster, head to the Treasure Hoard. Buy as many Paraversal Hauls as you can, open them, and take your treasure keys to the chest in front of Xur.

While you aren’t guaranteed a Red Border weapon from the chest, it has a decent chance of dropping them. Open as many as you can, and hopefully RNG will be on your side!

Once you’ve earned enough red border weapons, go to the Enclave and craft it! In order to unlock all of the perks you will have to level it up for a while, but once you do you can pick whatever perks you like, including their enhanced versions!
