Well, that was fun. After many NM runs I give in and throw down the plat for trade (get a decent deal after a bit of a push)... Do a NM run after that (couples hours later)... and I get another Animal Instinct. Seriously. That said... http://warframe.wikia.com/wiki/Animal_Instinct It's a must-have for Syndicate missions and generally all-around-awesome utility mod for a companion. Saves your Warframe space/points. Anyone interested, let me know!
