A blue whale can hold its breath a number of rounds equal to 10 times its Constitution score before it risks drowning.
A blue whale's massive tail deals more damage than a normal tail slap. The blue whale's tail slap is a primary attack and applies 1-1/2 times its Strength bonus to its tail slap damage.
A blue whale's fluke can deliver a powerful stunning blow. A creature struck by this attack must succeed at a DC 34 Fortitude save or be dazed for 1 round. If the strike is a critical hit and the target fails its save, it is instead stunned for 1d4 rounds. The save DC is Strength-based.
