The winged catfish is a homebrew aquatic monstrosity that ambushed the party’s skiff a couple of hours out from the Aurelian coast in session 18. Blue-scaled, “about the size of a giant catfish with wings about the size of Steven for them on each side” (Nick, [2]; pale eyes [5]; flies, swims, and breathes acid. Stalked the boat as an underwater shadow from the reef line onward [1] before surfacing two hours from coast [2]. Across three rounds it destroyed the party’s skiff (a combination of its acid breath and Caelumn’s bouncing Chromatic Orb; [21], downed Mike with 42 acid damage on a single failed DC 14 DEX save despite Mike burning a Luck Point and Inspiration for advantage [26], then dived back underwater and fled the encounter alive [11]. The DM jokingly called it “monkfish” once at [8]. Status: alive, fled. Open thread - the creature could return.
Overview
The winged catfish is a homebrew aquatic monstrosity that ambushed the party’s skiff in session 18 on the southbound sail toward the Aurelian coast. It is not statblocked against any vanilla 5e creature; closest references would be a winged aboleth or a homebrewed wyvern-fish hybrid. Nick (DM) introduced it at [2]: “you feel this creature that has been stalking you jump out of the water. It is not as big as the worm. However, it looks like a giant catfish with wings about the size of Steven for them on each side as it dives over your boat and turns around in the water, ready to strike.”
It had been stalking the party as an underwater shadow since the reef-line aftermath [1], seen and then lost. It surfaced two hours out from the Aurelian coast and engaged for three rounds before fleeing alive [11].
Appearance
Giant catfish-shaped body, blue-scaled [12]. Wings “about the size of Steven for them on each side” [2] - large enough to allow sustained flight and hovering. Pale, blank eyes (“and it’s just looking at you with blank pale eyes”, Nick, [5]. Large size (DM corrects from “huge” to “large” at [13]. The DM jokingly called it a “monkfish” once at [8] - table joke, not canon.
Combat profile (per s18 rounds 1-3)
- Acid-breath cone (recharge) - DC 14 DEX save; 45 acid damage on full failure, 22 on save [14], L953). The breath weapon recharged at the top of Round 3 [9], suggesting recharge 5-6 or similar. Mike’s failed DC 14 in Round 3 - taken despite a burned Luck Point plus an Inspiration die for advantage - was the 42 acid damage hit that dropped him to 0 HP and triggered Caelumn’s revive [15], L982-986). The breath weapon is biological in origin, not magical; the DM ruled at [4] that “dragon breath would be draconic magic. However, this is biological.” This is a per-type precedent and is the working canon going forward - Terry’s Elminster’s Illusion was retconned out on the same ruling [16].
- Slashing/acid bite - melee bite while submerged. Round 2 bit Mike in the water for 10 slashing + 3 acid [17]; the bite came with a flavour-only drag effect (no formal grapple condition, per the DM clarification at [18].
- Flight - flew above the water surface for the acid-breath positioning [3]; also dove and swam underwater (Round 2). Capable of switching between airborne and submerged on the same turn.
- Swim speed - high. Disengaged underwater on Round 3 and was gone [11].
- Resistance to Witch Bolt restraint - Caelumn’s Witch Bolt tether hit but the DM ruled “it is so ginormous that you can’t actually keep it under control with your witch bolt” [19]. Treated as flavour - damage still applied each round - but no formal restraint condition.
Session 18 - boat-destroyer
The catfish surfaced two hours out from the Aurelian coast and immediately fired its acid breath on Terry and Hugo for the cumulative starting damage of the fight [3]. Caelumn opened with a Witch Bolt (red-fire static reflavour) and sustained concentration; Steven hurled Chain of Conviction (saved); Hugo activated Winged Boots and flew up to engage; Mike Blessed three frontliners and jumped into the water on his bonus action. Round 2 saw the catfish dive and bite Mike (10 slashing + 3 acid); Hugo’s opportunity attack took 17 damage; Mike Misty-Stepped back to the boat. The pivotal Round 3 breath weapon failed for Mike despite Luck Point + Inspiration advantage - 42 acid damage, dropped to 0, revived same round by Caelumn’s 1st-level Cure Wounds for 11 HP [20]. The catfish then dived under and was gone.
The party’s skiff was destroyed by combined acid damage: the breath weapons over the course of the fight ate the hull, and Caelumn’s 1st-level Chromatic Orb (thunder, bounce variant) struck the catfish and then bounced into the boat at [21], accelerating the hull’s dissolution. Steven tried to mitigate with a Prestidigitation-cleaning Arcana check (13, succeeded enough to slow but not reverse the damage; [22]. The boat split in two underneath the party at [23] and sank, triggering the multi-hour open-ocean swim that took up the next stretch of session 18.
Status
Alive, fled underwater at [11]. Confirmed by post-encounter party dialogue: “we didn’t even kill that thing, did we?” “it fucked off” [24]. The creature’s nesting site, range, and any pack/lone-predator status are unknown. The DM’s note about Aurelian-trained dolphins being deployed against sea-going magic-users [25] is in a related vein but separate from the catfish itself, which is treated as a wild creature.
Open threads
- Where does it nest? Range unknown; could return for any future open-water travel through the Sapphire Sea.
- Solo or pack? Only one was seen; presence of others not confirmed or denied.
- Relationship to the Sapphire Sea bestiary - the reef-line bestiary (the Brinemaw Wyrm and friends) operated in a frost-zone biome north of the catfish encounter; the catfish does not appear to be cold-adapted (no frost-coding, no ice-water behaviour). Treat as a separate fauna entry, not the same biome.
- Whether the DM intends to circle it back - the catfish “fled” rather than dying suggests a future hook is on the table.
