Amy

Amy is an eldritch huntress of inhuman physiognomy and unknown origin who serves as the end boss of the Caverns. Though a voracious monster and fearsome opponent, her predatory exterior belies a playful, affectionate nature.

In-Game Description
"An unnerving looking woman with porcelain white skin that's unnaturally smooth and unblemished across her entire body. Purple marking surround her slim, faintly glowing violet eyes and then trail down to her neck, framing her face and giving her the appearance of wearing a pale white mask. Her petite nose rests in the middle of her face, and where her mouth should be, appears to be completely smooth."

"In place of her hair are instead a series of pale, swept back tentacles that occasionally twitch and writhe in the air as they coil around each other and slither down to her shoulders, giving them the unnerving appearance of featureless snakes twining on top of her head."

"Her B cup breasts are perfectly smooth, without any blemishes or nipples, and seem to completely defy gravity, remaining pert and perky no matter how she moves. The woman's pale, lithe arms end in disconcerting pure white clawed hands with no distinction to show where her fingers end and her long, segmented talons begin."

"Her slim waist is accented by a few twisting purple lines, breaking up the stark white coloration of her entire body starting from her midsection and complimenting her curved hips as they trail down her hips and lead into the dripping entrance of her pale violet pussy."

"A long, winding tail spirals out from just above her trim rear, widening shortly down its length before gently tapering to a purple, faintly crackling point that glows with a pale violet light as it gently twitches from side to side. Her long, flexible legs remain as flawless and smooth as the rest of her body as they gracefully end in vaguely humanoid, amphibian feet that seem to cling to whatever surface they touch as she walks."

"Her smooth back is covered in a symmetrical pattern of purple splotches that lead all the way down to the base of her tail before disappearing."

Strategy
Despite being an area boss, Amy's fight is largely optional, with a whopping 4 out of 5 options leading to an area clear on the first encounter. For players that have accidentally cleared the Caverns, Amy is always open to hang out and have sparring matches with the player.

Amy is a Stance-based Aphrodisiac boss, the majority of her damage will come from the sheer amount she does while in a stance. However, all of Amy's stance initiations start with a base 20 Power/Technique check. Players should prioritize boosting either their Power or Technique beforehand to comfortable pass the checks. High level players that already have a fair amount of points invested can instead focus on aphrodisiac resistance.

Amy has decent resistance to Magic, Pain, and is somewhat resistant to Breasts attacks. She has no resistance to Charm and will take an additional 10% damage from Seduction attacks. Due to not having an anus, Amy is immune to anal penetration, but can still be hit by skills that attack her butt. Ideally, the player should be using Allure moves while keeping out of Amy's deadly stances. Otherwise, skills targeting Sex and a hefty stack of Anaph Herbs will suffice. Make sure to also have some Ugli Herbs available in case of her Otherworldly Purr!

Note that using any Pain attacks three times in total (even in different fights) will cause her to immediately leave the fight and hold grudge against you during future encounters (similar to that after choosing 'Oh, sweet goddess what the FUCK is that thing?!' during her first encounter), until you apologize.

Amy and Perpetua
On the first encounter, the player will encounter Perpetua running away from Amy. The player will have 5 different options during this event.
 * 1) 'Nope.' (Run!), the player will run away from Amy on their own, leaving Perpetua behind. Perpetua eventually catches up to the player and latches onto their backpack, leading to the Maze Minigame.
 * 2) 'Nope.' (Grab Perpetua and run!), the player will grab Perpetua and run from amy, leading to the Maze Minigame. No affection for Perpetua is calculated in any of these scenes, so feel free to bully her as you wish...
 * 3) Offer your cock to Amy's writhing tongues, the player willingly sacrifices their self to Amy, letting Perpetua slip away. An oral scene will trigger, resulting in +3 Oral Fetish, +3 Monstrous Fetish, and +10 to Sex Sensitivity. This counts as a clear and you will have fully unlocked the Caverns.
 * 4) 'Oh, sweet goddess what the FUCK is that thing?!', primary bully option. Perpetua will be a bit disappointed, and Amy will not willingly interact with you afterwards until you offer your cock to her. This counts as a clear.
 * 5) Attack! Starts the combat encounter with Amy.

Maze Minigame
Once the player begins to run, the player will need to dodge Amy's pounce at least once, requiring a base check of 15 Technique. Afterwards, there is a short guessing puzzle on which direction to run to. Going in the wrong direction will result in another pounce check.

The guide to escape slightly changes based on the first direction.

If Left! is chosen first, go Right!!, if Right! is chosen first, go Left!!. Straight will always lead to pounce.

With the 3rd option, the rules are slightly different.
 * 1) Right!!! will lead to an immediate combat encounter with Amy
 * 2) Left!!! will lead to a pounce check
 * 3) Center!!! will escape the tunnel, this will count as a clear for the Caverns.

Voracious Huntress
Accepting this quest while exploring the Caverns allows you to have a rematch with Amy at the end of your run. This is essentially a repeat of her boss fight.

Scenes
Once the player has cleared the Caverns, they can meet Amy again either by choosing the "Voracious Huntress" quest while exploring or directly picking the "Visit Amy?" option in the world map. The former will lead to a repeat of her boss fight, while the latter allows you to more thoroughly interact with the eldritch girl.

While visiting Amy, you have the options to talk - or at least attempt to, as she prefers not to communicate verbally -, pet her, fight her for a repeat of her boss fight or have sex. Choosing the latter leads to a choice between offering her your cock, going for the 69 position or fucking her while you lead, all of them involving her tongues in various ways.
