I made a one-shot homebrew: break up a Cockatrice fighting ring.

It is hilarious fun.

Party is enlisted to help take down the people running the ring- and ideally get information about other rings. and free the Cockatrice without being attacked.

• First challenge - Figuring where the fights are happening. (I had the party witness a suspecious character with a cart turn off the road in their vision. but an NPC could give this info.) 
• Second challenge - figuring a way into the magically protected arena. (Only way in: have a cockatrice with you or a magically enhanced token of entry - obtained from a barman in a tarvern or shop)
• The protected area has a guards shack (#of guards relative to party size), a cockatrice barn, the arena, and the bad guys office. 
• I have an NPC working in the barn that actually loves these lizard-chickens and hates being forced to work here, helping the fighting ring.
• The arena has a bookie and two bouncer type thugs watching. the rest of the attendees are observers, cockatrice owners, and gamblers.
• Will the attendees placing bets help the party, flee, or help the bad guys?
• What happens if the Cockatrice escape the caged fighting ring inside the arena? I mean, it is more fun if they escape somehow ;-) 

Change what you want to make this your own. 

I'm planning to use 3-4 of these against my players soon. They're only level 2-3, so it should be fun. Even if everything goes terribly, the worst that can happen is that they're petrified for 24 hours. :) 

I can not wait to be a cockatrice as a druid!

These guys are gonna be the main threat in a One-Shot i'm doing. i'm going for something like a raptor from jurassic park.

I want a pet cockatrice.

As do I.

Im a dm and I got one in my campaign which was meant to be a semi boss, they cast talk with animals and got a charisma of 23 it’s there pet now 😂
