Frightful Fridays! Frogtober! Stellaruna

Hello and welcome back for day 8 of Frogtober, featuring illustrations by Hugo Solis (https://www.deviantart.com/butterfrog)! Today's frog (delivering on the theme of "star") deviates from the horribleness of the previous frogs, unless you happen to be an evil aberration, in which case, the stellaruna will make today a bad day. A stellaruna eschewed other celestial beings' watchfulness of and animosity toward fiendish beings, so it can seek out evil among the stars, especially evil perpetrated by unknowable elder beings. The PCs shouldn't have a problem with this creature (unless they're in the habit of summoning aboleths or worse) and may even find it a valuable ally in a pitched fight against some eldritch horror.

I hope you enjoy the stellaruna. See you tomorrow for day 9 of Frogtober!

A tapestry of stars covers this immense frog’s skin. Its eyes shine with the light of a star going supernova.

SPECIAL ABILITIES

Aberration Hunter (Su) A stellaruna gains a +4 racial bonus on attack and damage rolls, and opposed skill checks against aberrations. This bonus also applies to saving throws and spells originating from aberrations. In addition, if the steallruna identifies an aberration with a Knowledge (dungeoneering) check, it treats its attacks as possessing the appropriate qualities (including epic) to bypass the aberration’s damage reduction.

Crush (Ex) In addition to the listed damage, a stellaruna can create a 30-foot-diameter, 60-foot-deep pit where it lands, without harm to itself.

Starflight (Su) A stellaruna can survive in the void of outer space. It flies through space at an incredible speed. Although exact travel times vary, a trip within a single solar system should take 3d20 hours, while a trip beyond should take 3d20 days (or more, at the GM’s discretion)—provided the stellaruna knows the way to its destination.

Stellar Furnace Ray (Su) A stellaruna’s stellar furnace ray has a 240-foot range. This attack ignores resistance to fire. Immunity to fire still fully protects a target from this attack.

Void Ray (Su) A stellaruna’s void ray has a 240-foot range. This attack ignores resistance to cold. Immunity to cold still fully protects a target from this attack.

Where most celestial beings concern themselves with misery caused by the denizens of the lower planes, stellarunas saw what they considered a more disturbing problem in and beyond the firmament of the Material Plane. Vast, incomprehensible beings of terrible power and an insatiable appetite for chaos and devastation seemingly lurked in the places few creatures saw. Much like their mortal counterparts, stellarunas speaking of such beings were considered insane. They were ousted from their home plane, but this suited them well, since they desired to travel the Material Plane and thwart these awful beings. Stellarunas recognize their foes don’t pose an imminent threat like many devils, daemons, and demons do, but they believe these aberrant creatures present a more universal threat.

Stellarunas travel from world to world to root out less powerful aberrations and cults dedicated to the impossible beings they regard as deities. They sometimes get overzealous in their crusades against aberrations and wipe out whole communities tainted by cults.

Good clerics can use greater planar ally to call a stellaruna to assist with combat against an aberration with at least 20 Hit Dice.

Stellarunas have access to stars and the void of space, and are nigh unquantifiable when it comes to their size. They present themselves in a compact shape when dealing with other creatures, measuring roughly 25 feet long, and weighing 50 tons. As long as there are stars in the universe and they survive the massive battles they pick, stellarunas have infinite lifespans.
