I needed to buy rations for myself since I was the only one without. The market we visited had livestock.
Me: Can I buy a chicken and just keep it?
DM: As a pet? I guess?
I bought the chicken and named it Martha.
Me: Ok, can I buy armor for my chicken?
DM: …..Sure, why not. You’ll probably have to have someone repurpose a helmet for more gold.
Me: That’s fine.
DM: …There isn’t anything about a chicken’s base AC, so let’s just say 7 and the armor brings it up to 6.
Archer: THE CHICKEN HAS HIGHER AC THAN I DO!
Bard: What’s it’s name again? I need to write a poem about this.
