The Redrix’s Broadsword is capable of a 2-burst kill if you can manage to activate the desperado perk. That is how good of a weapon it is. Since Black armory is releasing in a week with Season 5, your chances of obtaining the weapon are only a matter 7 days. Don't worry by following our guide you can easily acquire the weapon before the next reset. Let's begin:
Step 1: ORIENTATION
For the first step, you have to get "200 Pulse Rifle final blows" in any Crucible playlist. You can use just about any Pulse Rifle for this step but we recommend you either use Graviton Lance or Inaugural address. The Inaugural address has outlaw and kill clip which makes it a beast weapon to use in PvP. Graviton Lance has a Black Hole perk that does High Damage on the 3rd shot and features Explosive payload. Only use Vigilance Wing if you have the complete Auto Catalyst.
Step 2: THE SHAPE OF THINGS TO COME
The second step requires you to reach "Heroic" Valor Rank. All you have to do is play Crucible and rank up until you reach Heroic. We recommend you play "Rumble" to rank up easily. The Rumble playlist requires you to place in the Top 3 position to count as a win. So just try to place in the top 3 to gain a win streak to get bonus points. Stacking the win streak 5 times will give you bonus points. That will make it much easier to complete this step. If you have reset your rank before then this quest will auto-complete after you complete a Crucible match.
Step 3: THE CANDIDATE
For this step, you need to get "75 double kills" in Crucible. I know this sounds like a lot of work but don't worry you don't really need to go for a kill. Just try to land as many shots as you can in multiple guardians. Even if your teammates manage to kill them after, that will award you with the double kill medal. It's also easier if you use a Rocket launcher, Telesto or Thunderlord.
Step 4: DEAD IS DEAD
For this step, you need to defeat "150 opponents" with precision final blows from any Pulse Rifle. We recommend you use Graviton Lance because it's easier to get a headshot with that weapon.
Step 5: FURTHER INSTRUCTIONS
For the fifth step, you need to defeat 50 opponents with Arc, 50 opponents with Solar, and 50 opponents with Void final blows in the crucible. Just use your super and get as many kills as you can.
Step 6: THIS PLACE IS DEATH
For the sixth step, you need to complete 25 Crucible matches in Quickplay, Rumble, and Competitive modes. Don't worry you don't need to win them just drop in a match and finish it. Listen to some podcast while you're at it.
Step 7: THE CONSTANT
This step will take 2-3 days since Shaxx offers 5 bounties per day and you need to complete 20 Crucible bounties to reach the next step. Just before we proceed any further. If you can manage to reset your rank 5 times and then complete step 7, step 8 will auto-complete and you can move straight to step 9.
Step 8: THE BEGINNING OF THE END
For this step, you need to Reset your Valor rank 5 times within a single season. I know this sounds like a lot of work to do in just a week but it's not. As I've said before all you need to do is play the Rumble playlist and try to stack a 5x win streak to get bonus points. A single reset requires you to earn at least 2000 Valor points. So that's 10000 Valor points for 5 resets. Play rumble because getting that 5x win streak can help you progress faster.
Step 9: THE END
That's it, just visit Lord Shaxx and get the Redrix's Broadsword. Go nuts in PvP with the Desperado perk.
