This blue-skinned creature swiftly floats out from a bank of mists on a carpet of blue and black smoke. It grins maniacally, the one eye dominating its face pursed in anger.

constant—true seeing

TACTICS
Before Combat The eye eater uses its spell-like abilities to confuse prey and get within reach to eye gouge.
During Combat Eye eaters do not fight to kill, they fight to maim—once a target has been deprived of an eye (or eyes; see experience palette below) the monster moves onto another. The only exception to this is when an enemy strikes an eye eater’s eye, at which point it aims to completely blinds their foe.
Morale When all creatures within its perception have been maimed, removed of an eye (or eyes), the eye eater flees.

SQ experienced palette, impossible flight, sound mimicry

ECOLOGY
Environment any (Aventyr’s Underworld)
Organization solitary, pair, or murder (3-6)
Treasure double

SPECIAL ABILITIES
Impossible Flight (Ex) It is completely impossible to see what exactly keeps an eye eater aloft, and even the cunning creatures are unsure of how they achieve flight so swift and perfect.
Experienced Palette (Ex) Eye eaters are quite strange and unless their prey wounds its eye or possesses more hit dice than the eye eater, it only takes one eye per creature it encounters. Should an eye eater’s single eye get wounded (AC 27, flat-footed 18; hp 8) it is immediately healed as soon as it completes a successful eye gouge.
Eye Gouges (Ex) Within the arms of eye eaters are long tendrils ending with hooked, serrated barbs. When uncoiled (a free action) the eye eater can replace any slam attack with an eye gouge. Eye gouges have a range of 15 feet and are melee touch attacks made at a -8 penalty; on a successful hit, a tendril impales the target’s eye. At the beginning of the eye eater’s next turn any uncoiled tendrils reel back into its arms (along with any eyes impaled by them). Tendrils have an AC of 12 and 10 hit points.
Creatures with one eye suffer a -4 penalty to visual-based Perception checks. A damaged eye is restored after the barb is removed (a DC 23 Heal check) and the creature receives a cure spell or other form of magical healing.

Eye eaters are some of Aventyr’s most mysterious and malicious denizens, often found wandering the Underworld but said to frequent even the most inhospitable regions as well. Enigmatic and unfriendly to virtually all races, these monsters quick descend on camps of adventurers (typically as they rest) and assault with dashes peppered by maiming strikes before disappearing when their quarry is blooded (and short of an eye each).

Mannstirge            CR 3
XP 800
CN Medium aberration (chaotic)
Init +5; Senses darkvision 60 ft.; Perception +10

DEFENSE
AC 20, touch 16, flat-footed 14 (+5 Dex, +1 dodge, +4 natural)
hp 22 (4d8+4)

OFFENSE
Speed 30 ft.; fly 30 ft. (poor)
Melee 2 claws +7 (1d4-1 plus grab)
Special Attacks blood drain (1 Constitution), claw probisci, double drain

TACTICS
Before Combat Mannstirges have been known to track prey for weeks, sometimes even months, waiting to attack enemies at night when they are most vulnerable.
During Combat These creatures are cunning but single-minded, seeking to isolate targets before begining the slaughter. A mannstirge releases a creature after it has dealt 6 or more points of Constitution damage.
Morale Mannstirges wing off into the night when reduced to 10 hit points or less.

STATISTICS
Str 8, Dex 20, Con 13, Int 13, Wis 15, Cha 9
Base Atk +3; CMB +2 (+14 grapple); CMD 18 (26 vs. grapple)
Feats Dodge, Weapon Finesse
Skills Acrobatics +13, Fly +9, Perception +10, Stealth +13, Survival +10
Languages Common, Undercommon
SQ diseased (as a stirge), lycanthropic empathy (stirges)

ECOLOGY
Environment any, temperate and warm swamps
Organization solitary
Treasure double

SPECIAL ABILITIES
Claw Probosces (Ex) When a mannstirge hits with one of its claw attacks, proboscis protrude from within its arms and bite into the target. The mannstirge loses its Dexterity bonus to AC and has an AC of 14, but gains a +8 racial bonus to maintain its grapple on a foe. A mannstirge that takes half its remaining hit points in damage automatically releases a grapple caused this way.
Double Drain (Ex) A mannstirge that hits a creature with both claw attacks in the same turn deals double damage with its blood drain ability.
Sanguine Feast (Ex) Mannstirges gain a +1 enhancement bonus to Constitution for every 2 Constitution damage dealt to creatures through its blood drain ability. This enhancement bonuses for 10 minutes.

Few scholars have been brave enough to study the mannstirges too closely, and those that do rarely survive. Fell predators of the night, the rumors and legends of their creation are myriad—some say that mannstirges are transformed stirges so fattened they cannot fly, while others claim that werewolves beset upon by swarms of the lesser creatures are transformed into flying monstrosities. Once a mannstirge finds a suitable territory in which to feed, it continues to attack prey there until killed or driven off from its lair.

Organization solitary, pair, fury (3-8), maelstrom (9-16)
Treasure none

SPECIAL ABILITIES
Lightning Stinger (Ex) A lightning wasp can fire a bolt of electricity from its stinger at creatures within 20 feet of it. Any target wearing metal armor takes additional damage (medium armor +1 electric damage, heavy armor +2 electric damage).
Lightning Swarm (Ex) A lightning wasp deals +1 electric damage with its sting and lightning zap for every lightning wasp adjacent to it.
Lightning Zap (Ex) Any creature that hits a lightning wasp in melee combat using a natural attack or metallic weapon takes 1d4 electric damage. Creatures grappling a lightning wasp take 1d4 electric damage on the first turn and 1 electric damage each turn spent grappling it.

Lightning wasps are curious creatures that can appear anywhere throughout Aventyr, though they almost always emerge from particularly vicious storms. The unnatural buzzing of their sizeable wings creates a drone throughout the air that roils like thunder as a maelstrom of lightning wasps descends on an area to hunt, scorching the land aflame with their electrified stingers before moving on to wreck havoc elsewhere.
