Head around the roots in front in front of you and continue to the North. This will lead you to a Shard Bank for you. You will need to feed it a high number of shards. Thankfully, there are a number of Shards that can be found in the area.
Immediately after you arrive there will be Primal Thralls coming after the team. You will also encounter Thrall Gunners coming out of Jennerit Warp Anchors that land around the area. You also need to deal with some Varelsi that have come into the area and have shields protecting shards. The shield will go down if you kill all the Varelsi.
Head over to the East then turn to the South to find a larger unprotected crystal. Break it to get a nice boost to the crystal
