I cannot endure this place any longer… Before I depart, a final offer for you.
Sleeper Simulant: a Fusion Rifle equipped in your Heavy Weapon slot. This weapon's laser tears through enemies and ricochets on hard surfaces. - Xûr, Agent of the Nine

An end will come, Guardian. Bring it about sooner with Telesto, a vestige of the Queen's Harbringers. This Fusion Rifle will attach projectiles to your foes and detonate with a delayed Void blast. Multikills with this weapon will drop Orbs for your allies. - Xûr, Agent of the Nine

You must adapt to persist, Guardian.

The Chaperone Exotic shotgun fires a single slug shot and grants an Agility boost when equipped. Your precision kills will grant a brief increase to Handling, Range, Rate of Fire, and Stability. - Xûr, Agent of the Nine

Warlocks: reshape the world and turn iron to gold with the Alchemist's Raiment. Collecting Primary Ammo will give you a chance to gain glimmer. Orbs collected when your Super is full recharge your grenades and melee. - Xûr, Agent of the Nine

Hunters: these Sealed Ahamkara Grasps are filled with Nightmare Fuel. They will provide you with an additional melee charge and your melee damage will have a chance to reload your Primary Weapon. - Xûr, Agent of the Nine

I have information, but I do not know yet if you are the one it is meant for... Titans: fly like the shadows with the Empyrean Bellicose. Aiming your weapons while in the air will hold you in place for a short time. Orbs collected when your Super is full will recharge your melee ability. - Xûr, Agent of the Nine
