Alright, ya, I am definitely likely the Cold Blooded trait.
From my tests it reduces the affects of Echolocator and other marker-type abilities by about half, which means that Echolocator barely stays on you for more than five seconds, making you incredibly hard to track with the skill and rendering a weapon's entire special effectively useless. Ninja Squid does NOT do this, and while it makes it hard to see you moving in ink, Echolocator is so prevalent and quick to charge that a lot of the time you will be seen even with Ninja.
