Motivation A blubble generally only attacks for its own survival. It has no malice towards its "prey" and doesn't even perceive itself as "attacking." However, it does seek out air-breathing creatures with the intent of getting them into its core in order to provide it oxygen.

During Combat If a blubble encounters Medium or smaller air-breathers it swims or flies over them with its mouth-like aperture wide open, trying to engulf and direct them into its core. A blubble generally avoids creatures larger than Medium-sized.

Morale If attacked a blubble defends itself only half-halfheartedly. If its prey (or other creatures) injures it, it lashes out with two semi-solid membranous appendages. If it is unsuccessful in subduing its prey or in fending off attacks from other creatures it gives up and moves on to find easier sustenance.

Engulf (Ex)

This functions as the engulf monster ability, except that creatures engulfed within a blubble are in no immediate danger of suffocating (due to the sphere of oxygen held within); however, unless freed, they will suffocate 72 hours later when the oxygen is depleted and replaced by carbon dioxide, poisoning the air-breathing creatures held within. The save DC is Strength-based.

Pressurize (Ex)

The intense pressure within a blubbles core may cause air-breathing creatures within to pass out. Air-breathing creatures which have been engulfed must succeed on a DC 23 Fortitude save or fall unconscious. The saving throw is Constitution-based.

Telepathy (Su)

A blubble can communicate telepathically with any sentient being within 100 ft. However, due to its simple mind it generally communicates only basic thoughts.

Water Mastery (Ex)

A sea sphere gains a +1 bonus on attack and damage rolls if both it and its opponent are touching water. If the opponent or the sea sphere is touching the ground, the sphere takes a -4 penalty on attack and damage rolls.
