This guide will let you know how to find and defeat Lephantis (Eris Junction) in Warframe.
You will need 5 Lephantis Nav coordinates to build the assassinate derelict key. It is one of the requirements for the Eris Junction.
The best place to get these nav coordinates is in Derelict Capture.
To do this mission, the first thing you need to do is buy a Capture Key and build it.
Make sure you equipped mods like thief ‘S’ wit or master thief on your Warframe.
Also, for your sentinels, you need to equip loot mods like Vacuum.
After that, go to Derelict Capture.
The Lephantis Nav coordinates look like regular Nav coordinates.
You can be found them in containers and lockers throughout the map.
You will need to complete the capture and then start searching.
After getting the final one, you can extract it.
