Today’s entry in Mythological Figures is one of Greece’s most beloved heroes, known far and wide for slaying Medusa and having the coolest gear: Perseus! He is not however the tamer of Pegasus—read onward to find out more about the invisible-capped decapitating founder of Mycenea.
Not unsurprisingly, Perseus is one of Zeus’ offspring. His mother is Danaë, a woman prophecied to beget the usurper of the King of Argos (Acrisius) and locked away to no avail. Not quite willing to cross the gods directly, Acrisius casts mother and son out into the sea in a wooden chest. They survive and are taken in by the fisherman Dictys, himself the brother of the king of the island he lived on (a fellow named Polydectes).
This Polydectes guy takes a shine on Danaë but Perseus won’t have it—so he tricks him, requesting all the guests of an upcoming banquet to bring him horses to win the hand of Hippodamia. Perseus has no horses and says “name the gift” and in reply Polydectes chooses the head of Medusa (the only mortal gorgon; the mythological kind, not the metal bull). Athena (the Goddess of Wisdom) instructs Perseus to find the Nymphs of the West (the Hesperides) to acquire the weapons to kill her and to do that he first seeks out the Graeae, three sisters of the gorgon—these are the old women that share one eye between them that you’ll probably remember from the Hercules animated movie from the House of Maus. To get them to share this information Perseus steals their eye, holding it hostage until they tell him where to find the nymphs.
Once Perseus reaches Hera’s orchard he’s given a knapsack to hold Medusa’s head, an adamantine sword from Zeus (a sickle-ended blade called a harpe), the Cap of Invisibility from Hades, a polished shield from Athena, and loaned Herme’s talaria (the winged sandals). [Editorial Note: Ridiculous haul.] When he gets to Medusa’s cave she’s sleeping and using the reflection of the shield, he safely sneaks up on her and decapitates the gorgon in her sleep. Pegasus—that’s right, the winged horse Pegasus—springs from out of her headless body along with the golden sword Chrysaor. Two other gorgons chase after him but he escapes by using the helm from Hades, going to Mauretania and seeking refuge from King Atlas. He’s refused and so Perseus turns him to stone.
Next he stops at Seriphos Island where the local monarchy (King Cepheus and Queen Cassiopeia) have angered Poseidon by the queen’s claim that her daughter Andromeda is as beautiful as the Nereids (sea nymphs). The god of the sea sends the cetus (“fishlike, serpentine, with a long muzzle. Alternate depictions may include long ears, horns and legs instead of flippers”; it’s not hard to see why this sometimes gets replaced with the kraken) to terrorize them until the oracle of Ammon tells them to sacrifice Andromeda to the monster. Perseus slays the creature and takes her as his wife despite her betrothal to Phineus who (get ready for the refrain) gets turned to stone in a quarrel at the wedding.
Perseus returns home to find that his mother is being violently pursued by Polydectes so guess who gets turned to stone. Afterward he returns his magical goodies, the fisherman Dictys becomes king of the island., and Athena puts Medusa’s head onto Zeus’ shield. Somewhere around here, Perseus fulfills the oracle’s prophecy and kills King Acrisius but exactly how is disputed—my personal favorite is that while showing off his new game (quoit which is basically horseshoes) he accidentally hits the man with a piece of thrown metal, but some sources have it as a discus, and then there’s another where Perseus turns both his step-father and step-uncle to stone (of course).
There’s more to Perseus—he swaps rulership of kingdoms, frequently replaces Bellerophon as the tamer of Pegasus (yay myth), founds Mycenae, and is killed by Megapenthes in vengeance for the death of King Acrisius—but this is already overly long and he’s got a Wikipedia page.
Design Notes: Why is Perseus a thief? So he can frequently reach into a bag to snag Medusa’s head and pull off his favorite trick! I’m of the mind that most classical heroes ought to have some fighter levels and to make him useful to GMs (because dropping a petrification thief onto the party is at best very mean) amped him up to extra attack level. Also friendly reminder that more D&D Greece stuff is on my website. The astute mechanics among you might notice his CR is slightly higher than the math suggests—I argue that “turn people to stone once a turn” is worth an extra bit of oomph, and generally give a fairly generous number of hit points for calculating when a statblock has Uncanny Dodge. Might even be worth boosting to 11, although be warned: PCs are not going to want to part with his equipment after they’ve got their hands on it.

Background: Nautical. Perseus is able to acquire passage on a sailing ship for him and his allies free of charge. He has no control over the ship’s route, departure, or return, and although no coin is required he and his companions do have to help crew the vessel.
Action Surge (1/short rest). Once on his turn, Perseus can take an additional action on top of his regular action and a possible bonus action.
Cunning Action (1/turn). Perseus can take a bonus action to take the Dash, Disengage, Hide, Use Object action, Dexterity (Sleight of Hand) check, or to use thieves’ tools to disarm a trap or open a lock.
Evasion. When Perseus is subjected to an effect that allows him to make a Dexterity saving throw to take only half damage, he instead takes no damage if he succeeds on the saving throw, and only half damage if he fails.
Feat: Fortune Points (3/long rest). Perseus can spend one fortune point to reroll an attack roll, ability check, or saving throw, or to force an attacker to reroll an attack made against him.
Improved Critical. Perseus’ weapon attacks score a critical hit on a roll of 19 or 20.
Magic Items. Perseus carries a reflective +1 shield, the Chrysaor (a golden vorpal shortsword), Hermes’ talaria (winged boots), and the helm of darkness from Hades (treat as a ring of invisibility).
Medusa's Head. Perseus carries the severed head of Medusa in a knapsack and can use his Cunning Action to wield the monster’s Petrifying Gaze.
Second-Story Work. Climbing does not costs Perseus extra movement. When he makes a running jump, the distance he covers increases by 3 feet.
Second Wind (1/short rest). On his turn, Perseus can use a bonus action to regain 1d10+5 hit points.
Sneak Attack (1/turn). Perseus deals an extra 14 (4d6) damage when he hits a target with a weapon attack and has advantage on the attack roll, or when the target is within 5 feet of an ally of Perseus that isn’t incapacitated and Perseus doesn’t have disadvantage on the attack roll.
ACTIONS
Extra Attack. Perseus can attack twice, instead of once, whenever he takes the Attack action on his turn.
Harpe (adamantine vorpal shortsword). Melee Weapon Attack: +10 to hit, reach 5 ft., one target. Hit: 11 (1d6+8) magical slashing damage that ignores resistances. When the creature has at least one head and Perseus rolls a 20 on the attack roll, he cuts off one of the creature’s heads. The creature dies if it can’t survive without the lost head. A creature is immune to this effect if it is immune to slashing damage, doesn’t have or need a head, has legendary actions, or the GM decides that the creature is too big for its head to be cut off with this weapon. Such a creature instead takes an extra 27 (6d8) slashing damage from the hit.
REACTIONS
Uncanny Dodge. When an attacker Perseus can see hits him with an attack, Perseus can use his reaction to halve the attack’s damage against him.

Medusa's Head. Perseus carries the severed head of Medusa in a knapsack and can use his Cunning Action to wield the monster’s Petrifying Gaze.
Petrifying Gaze. When a creature that can see the medusa's eyes starts its turn within 30 ft. of the medusa’s head, makes a DC 14 Constitution saving throw. If the saving throw fails by 5 or more, the creature is instantly petrified. Otherwise, a creature that fails the save begins to turn to stone and is restrained. The restrained creature must repeat the saving throw at the end of its next turn, becoming petrified on a failure or ending the effect on a success. The petrification lasts until the creature is freed by the greater restoration spell or other magic.
Second-Story Work. Climbing does not costs Perseus extra movement. When he makes a running jump, the distance he covers increases by 3 feet.
Second Wind (1/short rest). On his turn, Perseus can use a bonus action to regain 1d10+5 hit points.

A creature is immune to this effect if it is immune to slashing damage, doesn’t have or need a head, has legendary actions, or the GM decides that the creature is too big for its head to be cut off with this weapon. Such a creature instead takes an extra 27 (6d8) slashing damage from the hit.

Well, and the skelletons from 7th Voyage, and Jason & the Argonauts, of course.
