The Wellspring Farm

Four bosses each drop a weapon: Zeerik, Lightflayer gives the Void sniper rifle Father's Sins, Golmag, Warden of the Spring gives the Arc auto rifle Come to Pass, Bor'gong, Warden of the Spring gives the Kinetic combat bow Fel Taradiddle, and Vezuul, Lightflayer gives the Arc grenade launcher Tarnation. The triumph All The Spring's Riches asks for all four, and Hardware of the Throne asks to craft every Wellspring and Throne World weapon.

Warden of the Spring asks for a Master clear with each of its bosses active, and Defender of the Spring asks for a clear against each boss. Other triumphs include Speedy Spring (charge the Wellspring in Defend under three minutes), Crux of the Battle and Pop-a-Moth.

• The Wellspring run for 1 to 30 runs on Normal or on Master.
• A Self-play (Sherpa) extra and Normal, Express or Super Express speed.

• The Witch Queen expansion with the campaign finished.
• Bungie lists Wellspring among the expansion activities available now.

Is the Wellspring still playable?

Yes. Bungie's activity guide names Wellspring in Savathûn's Throne World as an expansion activity that requires The Witch Queen.

Do the weapons have Patterns?

The triumph Hardware of the Throne refers to crafting all Wellspring and Throne World weapons, so crafting applies to this set.

Does the Wellspring also drop glaives?

The exotic glaives other than the first one are acquired from the Wellspring activity, as Bungie's records state.
