Destiny 2 Titan BuildRocket Gundam

This is an extremely versatile build that can take care of add-clear, champions, and bosses with varying methods, while allowing for quick DPS dumps when stunning a champion or during a boss phase.

• Revision Zero (Preferably with 4th-times and Vorpal) for Anti-Barriers. While charging up the Hunter's Trace perk with precision hits you'll also be stacking rockets for your Hazardous Propulsion at the same time. When a champion is stunned you can use either Revision Zero, Hazardous, or your Rocket Launcher in any order to deal with champions.
• Indebted Kindness (Provided it's rolled with Jolt) for both Unstoppables and Overloads (with artifact and perk). Can be used for add-clear with it's high ammo, and will gain a damage boost when fired after a rocket barrage from the chest piece.
• Faith Keeper; This can realistically be swapped out for any Void Rocket Launcher, but this is for Champion and Boss DPS. With Expanding Abyss (artifact) your void damage is increased to weakened targets. Additionally, with Hazardous Propulsion, you'll gain bonus damage to any Rocket after firing a barrage. During a boss phase, you'll use your Twilight Arsenal super (which weakens targets), then follow up with a Hazardous Propulsion barrage, and then fire the Void Rocket Launcher. If you have an auto-load or reconstruction perk you can swap back to your Revision Zero and do a full Hunter's Trace dump, then swap back to the rocket before the buff/debuff runs out.
• The rest of the build is set for versatility. You can use Consecration for a wave of adds or take care of champions if you're close. The grenade can take care of Overloads (Facet of Dominance), or be consumed with the Unbreakable Aspect to get yourself out of a pinch if you need to reposition. Thruster's for faster regen to use your rockets more often (and I just prefer it personally).
