Tower I And Iii Survival Keys

[Zachles]

I'm looking to build Mag Prime (finally!) and I thought it'd be easier to recruit for them rather than wait for someone else to. I want to know the most effective places to get these keys from. Also, where do I get Frost Prime, and what places can I farm for those keys, too?

The best way to get them would be to do survival missions. Leave at 5 minutes for 30.54% chance to get T1 survival; 10 minutes for T2; 15+ minutes for T3.

 

You can consult the table here:

I suggest selecting a faction to farm these keys, so that, if you're interested in the other possible key, you can at least get that one if you don't receive the survival key.

 

I usually farm solo/private so that other people don't just go to extraction at the wrong time, unless you have friends to accompany you. Here are some locations I go to have an easy time:

 

Grineer: Apollodorus - Mercury
Corpus: E Gate - Venus

Infestation: Ara - Mars (good place to farm salvage if you need for the new clan techs).

Just do the Survival on Mercury. I was surprised to get a T1 key from it earlier.

Any survival mission will reward you (3/4 of the times) with a Key, T1 if you stay 5min, T2 if you stay 10min, T3 if you stay 15min

 

Btw i found all Mag Prime's BPs in T2 Survival < 5mins
