Collective Obligation is a must-have exotic and only drops from completing the final boss of Vow of the Disciple as a very rare reward. We are now offering a service for a GUARANTEED drop from the boss checkpoint in the raid. Please note that this service is limited to three boss checkpoint clears per week, but we will obtain it regardless of how many raids it takes to complete. Please note this will likely take several weeks to complete due to the RNG factor.
Collective Obligation is a PRIMARY VOIDexotic Pulse Rifle, which features a perk called Void Leech:
This weapon leeches Void debuffs when damaging targets that are suppressed, weakened, or volatile. Once charged, released to swap firing modes. In this mode, damage from this weapon applies the same Void debuffs that were leeched.
