తగినంత నీరు లేదు!* answers the summoned elemental, his voice akin to a roar composed of a million bubbles cavitating from an immense force stirring from the depths. The gigantic creature nevertheless begins to hammer the pool area containing the medusa with its massive watery appendages, each fall resulting in half of the underground chamber being splashed with gallons of water.
slam: 1d20 + 20 ⇒ (17) + 20 = 37 image on a 2: 1d2 ⇒ 1
slam: 1d20 + 20 ⇒ (17) + 20 = 37 image on a 2: 1d2 ⇒ 2
dmg: 2d8 + 9 ⇒ (4, 3) + 9 = 16
The massive elemental visits one solid hit upon the heroes' fiendish adversary!
I'm ruling here that creatures with a swim speed and either the aquatic or water subtype are not subject to the improved cover rules for foes attacking from land if they are in the same body of water as the target; in essence these creatures, although they may be large or huge or otherwise taller than the water's depth, have an innate way to move through water and have come to learn to effectively attack within it. Oh, and they don't do half damage for using their natural slam attacks, even if those are bludgeoning, nor do they take a penalty to hit with those. I have spoken. This is the way. :)
