Armamentarium Arc Titan Build Destiny 2 (S22)

An old build is back in Season of the Witch

Destiny 2 entered Season 22 with new content and some changes, as usual. An old Arc Titan build with grenades is back in business, strongest than ever, now with the help of Armamentarium.

The main focus of this Arc Titan build is the pulse grenades. With this, you will clear waves of ads and generate Ionic Traces, recharging your abilities. Thanks to the Armamentarium exotic arms, you have one extra grenade. That’s very important to make sure you have a grenade ready to throw all the time.

Meanwhile don’t forget to check our Reddit and other Destiny 2 guides, like the Solar Titan build with Synthoceps.

Recommended Gear: Armamentarium

For this new Arc Titan Build in Season 21, you want grenades so, the Armamentarium is perfect for that. Its exotic perk gives you one extra grenade.

Pick an Arc weapon of your choice, the ideal is that have the Demolitionist perk, which gives grenade energy with a weapon kills and reloads the weapon when you use grenades, the Forgiveness or Pardon are good choices, and of course the Thunderloard. The new exotic grenade launcher from the season, Ex Diris, is also great.
