If you're like me and have spent the last hour looking for Banshee's Workshop in an effort to get the new Exotic Heavy Bow (Leviathan's Breath), you'll be pleased to know a guildy as put together a video of the hidden location, to get your quest started. Take a look below. (This quest is only available for players who own the Season of the Undying pass)

Once you've done this, you can proceed with the following steps:

Step 2: WHERE ARE THE KEYS, SIR

Go back and talk to Banshee-44.

Step 3: INTRO TO SAFECRACKING 101

Simply complete Gambit matches or Strikes. Completing Nightfalls or Gambit Prime matches completes this step faster (only two needed)

Step 4: ADVANCED SAFECRACKING 101

Kill Vex or Cabal with precision bow kills. Head to the Vex Offensive on the Moon.

Step: ECONOMICS OF WAR

Complete a unique version of The Arms Dealer strike in the EDZ by recreating the conditions he first set the code under.

Economics of War: The key generator needs just a little more data before you’re ready to return to Banshee for final authentication. To further limit the possible codes the generator can create, you’ll have to recreate the conditions under which Banshee programmed the first codes: fighting Red Legion forces during the Red War. Complete an epic reprise of strike “The Arms Dealer” in the European Dead Zone on Earth.

Step 6: APPLIED CRYPTOSECURITY

Return to Banshee and tell him you’ve done everything he’s asked.

Applied Cryptosecurity: You’ve completed all the necessary calibrations on the key generator. The only thing remaining is a biometric authentication from Banshee. Return to Banshee-44 in the Tower.

Step 7: MARTIAL ARCHERY 401

Return to Banshee’s workshop to pick up Leviathan’s Breath.

Martial Archery 401: Return to Banshee’s workshop to claim the Bow.
