You transform yourself into a living incarnation of water. While in this state, you are immune to any physical damage, and have Resistance 1 towards Lightning damage, but suffer a Vulnerability 1 to Cold damage. You can seep through even the smallest crack, though moving through a space more than two sizes smaller than yourself requires that you Squeeze Through. Your own physical damage is reduced to d4s, regardless of what it would normally be, and you can only make Unarmed Combat attacks.
