(To roll d40 roll a d20 and d6 together. If the d6 is even, take the value on the d20 as-is. If the d6 is odd, add 20 to the d20's value.)The pool is a...
1 Natural spring 10' deep, brilliant emerald, and perfectly clear. Breaks curses, lifts enchantments, and physically restores anyone who drink or bathes in it. Undead can't come within 30's of its edge.
2 6' wide man-made well bored 30' into the living rock. The virulently cursed jet black water is perfectly level with the stone rim. Grants immortality to anyone who drinks or bathes in it, but makes them count as undead to magic and anyone they meet. Grants wishes that mostly turn out okay if offered a coin. 13' deep layer of coins at the bottom.
3 Six separate wells carved in a circle, each 7' wide and 11' deep. Full of murky pale green mineral water, blood-warm and breathable. Complete prolonged immersion heals spiritual damage and lifts curses. 1 hour submerged restores 1 point of lost INT, WIS, or CHA. 1 day submerged restores 1 lost level.
4 Perfectly smooth undisturbed pool of violet and black water. Superheated and steaming if you're outside but immediately cool and brisk once you're fully submerged. Portal to hell. Climbing out is a bitch.
5 Shallow 20' square basin of quartz quicksand, each grain a perfectly spherical bead. Moves and ripples on its own. Stills and acts as a scrying mirror when a thinking being touches it. No limit on range.
6 Cement pond choked with royal purple waterlilies. Smell wonderful, have hallucinogenic and euphoric pollen. Swarming with magenta fireflies that sequester arcane power in their bodies. Eating them restores magic but makes your mouth glow neon pink.
7 Muddy pool with irregular banks, full of rust-orange water that smells like iron. Erupts in a geyser every 20 minutes. Turns anything that touches the water inside-out.
8 Convoluted metallic clockwork basin full of light machine oil. Restores anything placed in it by rewinding time. (Has settings to accelerate time too, it's just in reverse gear at the moment.)
9 Five-tiered fountain of faceted crystal running with streams of glowing water. Throws off thousands of tiny rainbows. Water can be bottled and carried as a light source, counts as daylight.
10 10' x 20' rectangular reflecting pool fed by a semi-circular basin fountain mounted on the wall. The sides and bottom are decorated with complex mosaics in all shades of gray. Randomly changes the color of anything that touches it. Leaches all color from items submerged more than 3 times.
11 20' circular well of dressed sandstone blocks full of faintly luminous champagne-colored water. A golden statue of a kneeling man with cupped hands raised to his mouth lies on its side at the bottom. The water turns whatever touches it to solid gold.
12 Deep 40' square pool of viscous wine-red liquid at the bottom of a stepwell. Drinking it has no immediate effect. Resurrects you the next time you die. If there's not enough of your body left to salvage, you're reconstituted in the pool.
13 Small round well of clear cerulean water 20' deep with spools of silver thread lying on the bottom. Contains an underwater labyrinth. You can breathe inside as long as you're holding a spool, but all movement is at underwater speed.
14 Tranquil cattail marsh, knee deep and 150' across full of arrowroot, orchids, and sturdy logs. Home to thousands of tiny wish-granting frogs.
15 Flooded impact scar of a meteor, lined with cracked plates of fused glass and surrounded by gem-quality tektites. The water's contaminated with an extraterrestrial virus that absorbs anyone touching it into a hivemind and dries their blood to powder in a week. Apologetic about it.
16 Average suburban swimming pool with a diving board and robo-skimmer. Strips the magic and enchantments from anything dipped in it, making the object the most mundane and unremarkable version of itself possible. Works on normal decorative details and people's charisma too.
17 Turbid charcoal gray lake, its shores covered in smooth fist-sized stones. Small boats, rafts, and floats rest half-beached at the water's edge. Touching or crossing over the water tears your soul from your body and incarnates it in the form of a symbolically appropriate animal. The change is permanent.
18 Hexagonal pool tiled in mica-flecked black marble with steps leading down into the water. Complete immersion binds a victim's soul inside their body, rendering them unable to die no matter how severe their injuries are.
19 Upwards-pointed parabolic dish of pink granite with a series of tiny mouths carved around the rim. The surface is raised in the concentric circles of a standing wave. Absorbs and records everything said within 100 miles of it. You can hear the recordings clearly if you dunk your head under, just indistinct whispers above the surface.
20 15' wide octagonal pool of crystal clear water decorated with colorful geometric mosaics along the sides and bottom. Looks shallow but is infinitely deep. You can see the bottom perfectly but never reach it.
21 12' long kidney-shaped basin of smooth white porcelain filled with a warm thick sterile saline solution. The sides are gently curved and rise a few feet above the liquid's surface, making it hard to climb out. Increases the size of living things. The effect is more powerful the smaller a creature is. Humans might only grow a few inches while microorganisms become giant.
22 Sandy-bottomed cenote of brackish sea green water thick with bioluminescent kelp that grows back instantly when cut. It's delicious, nutritious, and keeps for months when dried.
23 Plunge pool of a 50' tall waterfall that flows in reverse. Water from the pool reduces gravity's pull on the drinker by half, samples taken from higher in the falls are more powerful. Water from the very top of the falls completely negates gravity.
24 45' wide semicircular wading pool of opaque bubblegum pink serum fed by a rusty pipe coming out of the wall. Turns anything that touches it into stuffed animal version of themselves.
25 Circular bowl-shaped glass font 12' across with waist-high walls full of slowly-churning maple syrup. Occasionally visited by giant ants.
26 Jagged flooded crevasse of dark indigo-black water. The water's alive, actually an elemental in the form of a giant moray eel.
27 Gigantic white marble bathtub with gold faucets and drain plug. Can easily fit 20 people. When full lets you travel to any other body of water. If you have a portion of the tub water kept separate and protected in a container you can return to the tub but otherwise it's a one-way trip.
28 15' x 30' rectangular pool 50' deep and glowing with Cherenkov radiation. The gently-circulating water was originally mundane but has become magical, having been irradiated for centuries by the dozens of magic swords embedded in the pool bottom like spent fuel rods.
29 Natural ground-fed spring of frigid sky-blue water, sand and sediment roiling at the bottom. Occasionally bubbles up random toys.
30 Irregular stone pool of liquid amber with a convoluted bottom of glacier-scoured grooves. Hundreds of prehistoric creatures are suspended inside, held in stasis. They wake within minutes of being pulled from the amber.
31 Septagonal quartzite pool 10' on a side and encrusted with clusters of glittering crystal points. Converts non-mineral material into gem quality crystals of random minerals.
32 Steaming hot spring of milky white water with a metallic sheen. Lets you speak with the dead when the surface is completely still.
33 15' deep crater flooded with luminous silvery water. Curses whoever touches it with lycanthropy. If they've been bitten by something since the last moonrise they become a were-[that creature] instead.
34 Deep cold natural spring festooned with stalactites and stalagmites feeding a subterranean river. Home to a giant catfish named Clement who causes earthquakes when he's upset and accurately predicts the future when he's happy. Will do just about anything for processed fish food pellets and junk food.
35 Round cast iron basin 13' across and 5' deep, coated with an iridescent layer of oil and full of cobalt-tinged flames. Surrounded by neatly tended rows of popcorn.
36 Star-shaped pond full of pearlescent lilac oil that randomly swirls, stops, and reverses direction under its own power. Anything that touches it becomes unstuck in time. No control over the effect at first.
37 Massive 11-sided oak vat made of interlocking staves taken from used barrels and casks. Full of dark beer, the bottom layered with rose gold votive figurines of bundled wheat sheaves. Overpowering smell of baking bread. Home to a displaced harvest goddess.
38 Triangular well 8' on a side with midnight blue water full of floating silver flakes. Transforms the drinker's body into living liquid silver that can shapeshift into any form.
39 Waist-deep white-tiled channel 5' wide cut in a complex meandering loop that covers a 70' x 40' area. The refrigerated opalescent coral fluid circulates through the course in a gentle current. It's a liquid computer that holds massive archives of data from multiple worlds and across millennia. Intelligent, with a true AI and a verbal/holographic interface. Heartbreakingly lonely.
40 Ostentatious multi-tiered platinum fountain with dozens of jets shooting interlacing laminar arcs of water, glittering with threads of shifting color like wisps of ink that never disperse. Reads as extremely magical and makes anything that touches the water also appear to be magic, but doesn't actually do anything. Looks impressive though.
