Cosmology farm destiny 2

Luckily for players, the Duality dungeon is fully farmable regardless of how many clears they had that week.
In other dungeons, players can only get new loot on their first time running the dungeon each week, and subsequent clears would just grant them an item they already have.

As players are exploring the new content of Destiny 2:

Thankfully, there’s a new world activity that’s perfect for farming the catalyst.
When you load up Destiny 2, head down to the Winding Coves in the southern portion of the EDZ.
This 980 activity typically has anywhere from 4-7 players participating at any time, so you have a lot of people to heal.

Like some folks suggested, Altars is a good place for cosmology kills.
The spot I used was K1 Revelation, the Sorrow's Harbor lost sector, which has a lot of clustered hive in it, and you don't have to compete for kills like you might if there are other people looking to farm kills at Altars.
It is.
