Warframe‘s Necralisk is home to the Entrati family, a group of Orokin affected by the Infestation that spread throughout the area. Deimos also houses a series of dangerous fauna, including the elusive Medjay Predasite.

In Deimos, capturing fauna with your Tranq Rifle’s help will yield tags corresponding to the animal you just captured. The Son is the Necralisk’s resident hunter, and changing tags with him will give you tokens to raise the Entrati standing. You’ll also need one Medjay Predasite Tag to level your reputation with them and reach rank three (Associate), yielding helpful rewards. Here’s how you get Medjay Predasite Tags in Warframe.
