The Quest for Growth has arrived in Destiny 2, giving us all access to the Ruinous Effigy Exotic Trace Rifle, as long as we can track down some of Savathun's puppets. You will need to defeat 15 of them as part of the quest, and you can find them in different locations, but only those killed on Io and Titan will count towards mission progress.
Savathun Puppets are normally linked to the Contact public event, and you can spawn one or two during that event. However, some changes have arrived in Destiny 2, and now you can find Puppets and Disruptors roaming the areas of Io and Titan that don't have an active Contact event.
Sometimes you will come across an easy to manage solo puppet, or you may find Disruptors with Taken Blights. If you kill the Burns and then the Disruptors, it will cause a puppet to appear which you can then remove.
So to repeat
- Travel either to Io or to Titan
- Consult the map to see where the public event is located Contact
- Head to an area WITHOUT the public event
- Drive on your sparrow until you find a disruptor or a puppet
- Sometimes you will see a message on the screen telling you that a disruptor has appeared, which is a nice indication of the game that you are in the same area.
- Kill the disruptor or the puppet
- Rinse and repeat
And that's all. Like a lot of things in Destiny 2, we'll just need to rectify them, but it won't take long using this method. Contact events take too long to complete, while you can get five or six kills in about 10 minutes quite easily this way.
