Reaching lephantis?

[(XBOX)Magnesium 360]

Hello. So I have one junction left, to eris. Requirement, defeat lephantis in orokin derelict. Now I understand you need a key to get to his mission node. If you have a party, does everyone have to have a key, or can someone with a key "taxi" me to him? It says it requires special nav resources to make the key. How are these resources found in the derelict. Are they from the vaults, are they mission rewards or drop from any mob? Any info would be most appreciated. Currently this seems like a difficult and time consuming task. Thanks tenno.

Only one person needs to have a key to access the Derelict.

The special Navs you need are Lephantis Nav. Coords. and ddrop from pretty much all Infested maps.  If you don't have access to one, you can run the Maroo weekly mission.  You have the chance of getting a Derelict map and you can get some from there (break containers)

You can be taxied, yes, but to find the nav coordinates, you just play the Derelict missions and they'll drop. It takes an hour to craft the Assassination Keys, but eh. That's nothing compared to some times.

Only the person who starts the Orokin Derelict mission needs a key, the others get a free ride.  The Nav Coordinates for general Orokin Derelict missions drop in any mission out of breakable containers.  The specific Lephantis Nav Coordinates drop from breakable containers in any other Orokin Derelict mission, and you'll need 5 of them to craft the Orokin Derelict Assassination Key.

All the Orokin Derelict mission keys take 60s to craft, except the Orokin Derelict Assassination Key which takes 60min to craft.  Once you have a key crafted, the Orokin Derelict shows up in the upper right corner of the Star Map!

OK cool. Thanks for the info guys. I'll try a taxi if not I'll farm. I have a good set up so I can't call it full taxi, more like a uber lol. So close. I just want my last planet unlocked lol.
