D.A.R.C.I user also gets +15% damage after granting five stacks to a teammate.
Dead Messenger, Hard Light, Borealis
The Fundamentals:
New effect: Grants a 30% damage buff (10% in PvP) to this weapon for 10 seconds when you apply or receive an elemental keyword that matches the currently selected damage type of this weapon.
Borealis only: Increased Stability by 20 and Aim Assist by 10 to permanently grant it the Void element bonus that it will no longer have access to.
Delicate Tomb
Increased the chance to make an Ionic Trace from minor combatants from 4% to 10%.
Increased the PvE damage bonus on the Tempest Cascade shot from 30% to 100%.

Increments off both shots and melee hits.

Edge of Action
Effects of Destabilizing Rounds trait added to intrinsic perk.
Edge of Intent
Effects of Incandescent trait added to intrinsic perk.
Added Cure pulse to special shot impact.

Legend of Acrius
Reduced spread angle by 33%.
Increased maximum projectile range from 12 to 18 meters.
Lorentz Driver
Picking up a bounty tag now grants one ammo to the mag.

Returns to adding one ammo per tag on extensions while the buff remains active.
Lord of Wolves
Increased range, reduced base damage.
Removed accuracy penalties from standard fire mode.
Release the Wolves now triggers on hip fire instead of special reload:
Fires full auto.
Greatly increased damage and rate of fire.
Reduced accuracy and range.
Catalyst:
Reload Speed and Stability boosts are now built in.
When Release the Wolves is active, dealing damage to targets scorches them.
When ADS, defeating targets spreads scorch to nearby combatants.
Quicksilver Storm
Reduced shots required to trigger a rocket by 17%.
The Fourth Horseman
Reduced the rate of fire slightly to give more control over wasting shots.
Loads ammo from reserves to the magazine per kill.
The Queenbreaker
Players can special reload at any time to swap between scopes.
Marksman Sights retains the previous behavior of firing a single shot that chains to nearby targets and blinds them.
The range of the chain has increased from eight to 10 meters to make chaining easier.
Combat Sights now alters the weapon to fire a three-round burst at a charge time of 533. Sustained damage on a target decreases the charge time of the weapon down to 300 charge time (with no loss to damage), useful for quickly dealing damage to bosses or other high health targets.
The scope that you select in the inspection screen will determine which scope is active by default when spawning into an activity.
The Colony

Increased number of bots spawned by one for all enemy tiers except players:
Player: One
Minor: 1->2
Elite/Major: 2->3

Added behavior to Reign Havoc perk:
Final blows with this weapon generate lighting strikes from above. Lightning strikes grant a stack of Bolt Charge. Strong against Overload Champions.
Telesto
Harbinger's Pulse:
Now only refills Telesto's ammo from reserves (instead of Telesto and your Kinetic slot weapon).
Now triggers with any Void final blow.
Final blow requirement increased from two to three, however Telesto final blows count double (in other words, will trigger from two Telesto final blows, one Telesto final blow plus one other Void final blow, or three other Void final blows).
Multikill timer increased from two to 4.5 seconds.
Catalyst
New perk: Harbinger Seethe
After three activations of Harbinger's Pulse, special reload the weapon to cause a rain of Telesto projectiles on your next direct hit.
Vexcalibur
Triggering 'Perpetual Loophole' (by scoring a melee kill while your overshield is active) now also fills your Glaive energy to full.
Slightly increased Void Overshield trickle-on rate to nearby allies and yourself when guarding.
Increased the potency of Vexcalibur’s innate advantages against the Vex.
Vexcalibur's secret damage bonus when striking with its projectiles against a certain enemy faction has been increased from 10% to 25% to match Wish-Ender and Malfeasance.
Vexcalibur now briefly disorients non-boss Vex with its melee attack.
Wardcliff Coil
New intrinsic effect:
Grants one stack of Bolt Charge to all nearby allies for every two rockets fired (four stacks per trigger pull).
