This Mastery should be taken as soon as possible, as it not only buffs your survival by an insane amount, allowing you to play more agressive and thus do more damage, but also gives you detection, which means you do no longer need to rely on the other heroes or the BC for detection. The optimal time to take this mastery is when you reach level 40, if you're good enough to squeeze out the damage score for it.
