Hieracon and Triton for T3 and some T4 keys.

 

Draco for T4 endless modes.

 

Augustus for all the other T4 keys.

 

You'll generally find other tenno on these nodes, for better or worse.

So I tried Hieracon for the keys, but I only get T4 keys. Where do I get a T3 Exterminate

[Sloan441]

Hieracon or Triton.

 

It's just RNG. I usually get T3 keys there and only rarely see T4 keys. Just the way of things.

 

This isn't a short term project. If you're farming keys on these nodes, you need to keep doing it for weeks, if not longer. Two to four sessions every day. That's how you build up a base of keys to work from when a prime access comes around.

Trition is your best choice for T3 keys
