Absorb Energy (Ex)

Masura absorbs energy attacks that damage her, including negative energy attacks. Damage blocked by one of her resistances or immunities instead heals her an amount equal to the damage dealt. She may absorb only one kind of energy in this manner in a round. The first type of energy that affects her in a round (whether or not it penetrates his immunities or resistance to actually damage him) sets the type of energy she absorbs for that round. Hit points gained in excess of her normal maximum are lost. Masura cannot gain healing from energy effects generated by herself.

Gift of Life (Su)

Masura has potent healing powers, but she sometimes has the need to give even more of herself when the need is great. As an action, she can use mass heal or true resurrection, but doing so causes her to take a -4 cumulative penalty to Con. This works like ability drain and this penalty stacks. She cannot heal herself when using these abilities. This penalty goes away after she has complete rest, but if this penalty reduces her Con to 0, she dies immediately after using this ability.

Glittering Chaff (Su)

Masura can shake loose a cloud of glittering motes in a 150-foot radius cylinder below Masura, up to 300 feet high. This affects creatures as both glitterdust and holy smite, using a single saving throw.

Hurricane Gust (Ex)

If Masura hovers in place, she can create a massive gust of hurricane force filling a 300-foot cone until the beginning of Masura’s next turn. This wind deals 42 (12d6) bludgeoning damage, or half as much on a successful saving throw. All fires in the area are extinguished and all ranged weapon attacks passing through the cone automatically miss. This wind is equivalent to a windstorm.

Poison (Ex)

Sting—injury; save Fortitude DC 37; frequency 1/round for 6 rounds; effect 1d4 Constitution damage; cure 3 consecutive saves. The save DC is Constitution-based. A creature that fails its save glows blue as if shrouded in faerie fire until they succeed on their saving throw.


Environment warm forests
Organization solitary, court (Masura plus 2-4 nymphs, two of whom are shamans of 4th to 10th level)
Treasure incidental

This enormous moth spreads its iridescent wings to an impossible span, gleaming with a radiant cerulean glow that carries the warmth of life within it.

Masura is a spirit of life and renewal, reproducing herself asexually and growing through a life cycle from larva to cocoon and then maturation into her mature moth form. If she is killed, a massive egg of glowing yellow and blue rings emerges from the remains and disappears, teleporting to hidden location where she will hatch as a new larva within 7 days, slowly growing to maturity once more.

Masura, the Empress Moth, is a mystical creature, an entity of life and peace and communion with the world and with nature.

She appears as an immense blue moth covered in silvery hairs shot through with gold, with luminous silvery wings that glow a radiant blue in response to the intensity of her emotions. At full size, Masura is more than 120 feet long and weighs over 10,000 tons, with a wingspan of nearly 300 feet.

Unusual for kaiju, which often are nearly immortal simply due to their great size and power, Masura embodies the natural cycle of life, death, and rebirth. She has died many times throughout the ages, each time giving birth to her own new incarnation first as an egg, then as a massive larva, and finally weaving a cocoon and emerging in her fully grown moth state.

She communicates empathically with other kaiju, seeking to quell their rampages or join forces with them against powers that threaten the entire planet, and she even has been known to sacrifice herself to sustain and restore her allies so they can continue the fight.

Masura is revered by the fey, and she is sometimes attended by a small cadre of nymphs who observe her life cycle, safeguarding her egg and cocoon when necessary, and negotiating with others who are not receptive to Masura’s empathic overtures. These nymphs often appear identical, though whether they are truly related or simply put on this mask for outsiders is unknown. Their often petition their insectoid mistress in song, pleading for her aid when troubles arise and she must rise from her slumber to aid them.

Masura is a healer and protector more than a combatant.

However, when pressed she uses her powerful wings and spell-like abilities to disperse enemies. Against enemy spellcasters, she strikes with her powerful melee attacks. She uses her flight to full advantage, and will not hesitate to create distance, though she is not fearful of death or defeat.
