When gaining shields from either placing an egg or when an egg dies the shield only last 10 seconds.

Confirmed in Regular Game
Suggestion Make this talent 35% of base health. The best use for this talent is to give murky a chance to get his octo off in places where he would get bursted down too quickly. It also allows for murky to go in and get away at low health. Drop an egg to get enough shield to come back in. In almost all other cases fish tank is superior.
