Truth Catalyst

Once installed, the catalyst gives the weapon Reaper's Tithe: several simultaneous final blows queue up a stacking damage buff, whose timer starts on the next shot and is extended by further final blows. Group kills with one volley are what the perk stacks on.

Prototype Trueseeker is the intrinsic of Truth: rockets track targets you lock onto while aiming down sights, and landing hits with a full magazine grants ammo and powers up the next magazine with stronger tracking, stability, fire rate and cluster bombs. Grenades and Horseshoes: projectiles detonate when they pass close to their targets. The other fixed perks on the weapon are Volatile Launch, High-Velocity Rounds and Composite Stock.

The catalyst drops in Vanguard, Gambit and Crucible activity, and it is completed by defeating targets with Truth. Progress shows on the catalyst's record in the Exotic Catalysts section of the Triumphs screen.

• Truth catalyst, unlocked and delivered to your account, without the masterwork step.
• Extras on the order form: Add Catalyst Masterwork.

• Truth already unlocked on the account, because the catalyst is slotted into that launcher.

How do I get the masterwork too?

Use the extra named Add Catalyst Masterwork. Without it the order covers the catalyst itself.

How does Prototype Trueseeker work on Truth?

Rockets track targets you lock onto while aiming down sights, and landing hits with a full magazine grants ammo and powers up the next magazine with stronger tracking, stability, fire rate and cluster bombs.

Where do I get Truth itself?

Truth is sold in the Exotic Archive at the Monument to Lost Lights, for an Exotic Cipher and Glimmer. Buying it needs the Forsaken Pack. The catalyst fits that weapon alone.
