Croc Shock: A Giant-Alligator Creature Feature: A 5e One-Shot Adventure for Small Groups - 2-3 Players, Levels 2-3, Zero Prep & GM-Ready (Paperback) (ISBN-13: 9798184835655)

Ready to run tonight: a thirty-foot blighted alligator is loose, the dam is cracking, and the whole valley has one afternoon before it goes under.

Your players come to Lake Glimmerglass for a lazy weekend at a faded lakeside inn - fishing, a famous bottomless drink, a little peace. What they find is a town being eaten. Generations ago a greedy merchant guild secretly dumped alchemical blight into Hoover Creek. It pooled at the bottom of the lake, fused into a glowing crystalline Core, and mutated a common alligator into something out of a tavern legend: Old Glimmer, thirty feet of armored, glowing, gloriously bad-tempered death. Now the creature's territorial thrashing has cracked the Hoover Creek Dam - and that dam is the only thing standing between the valley and the flood.

Your table has one afternoon to cross the lake, fight their way to the dam, and stop the rampage before the water wins. The twist that gives this one-shot its heart: the monster you were sent to kill is a sick animal that can be saved instead of slain - and the players who figure that out in time earn the best of three endings. It's a campy monster-rampage romp that curdles into real stakes and lands on a genuine choice, and it's a complete fifth edition adventure you can run completely cold.

A one-shot with a real arc. It opens as broad comedy - a conspiracy-minded bait-shop keeper who turns out to be right, a disgraced scholar nursing a grudge and a bottle, a constable badly out of his depth. Then the laughter curdles: people are already missing, the dam groans louder with every scene, and the glowing gators stop being funny. By the time your party wades into the drowned lodge and down to the creature's lair, it has quietly become a monster movie with genuine weight - and the finale turns on a hard call: destroy the Core and kill the beast, contain it and let it live, or carry it back to the deep and defer the reckoning. Your players will laugh, then flinch, then argue about the right thing to do.

Everything is built for busy Game Masters: no prep, no homework, no rules to look up mid-session. Hand two players a ready-made hero each, put the Dam Integrity counter where everyone can see it, and start the afternoon.

Built to flex: run it for two players or three, as a one-night drop-in or the cold open of a longer campaign, and lean into the camp or play the dread straight - the structure holds either way.

What's Inside:

• A complete 80-page adventure for 2-3 players, levels 2-3, in a single 2-3 hour session
• Five battle maps - a regional overview of the lake plus a map for every key location
• Six fully statted creatures (including a three-phase boss) and four named NPCs, all fifth-edition and SRD-compatible
• Four ready-to-play pre-generated characters - any two of them form a viable party
• The Dam Integrity Counter: a single visible tension dial that paces the session and tightens the screws as the dam fails
• A branching middle act - cross by boat or slog through the swamp - that changes the texture of the run
• A three-phase boss with two honest ways to win, kill it or contain it, plus a tense six-round dam-break escape
• Three distinct endings, six opening hooks, "What If?" contingencies for off-the-rails tables, and campaign seeds to keep the story going

Perfect For:

• Busy Game Masters who want a quality session with zero prep
• Small groups, two-player duos, and drop-in one-shots
• A monster-movie game night with a giant beast - and a sympathetic one - at its heart
• New GMs who want a complete adventure with the math already done and every encounter stress-tested

No prep required. Drop it into any fifth edition campaign, hand out the pre-made heroes, and run a complete monster rampage tonight.
