[@XxFellsingxX] Medieval petpets I see! Are you planning to be from Meridell? I'll get to work on some stat blocks for these, but feel free to spitball ideas.

For the Gallion: As it says it's a 'little' guy I am going with the small size. It mentions having a nasty bite so maybe adding acid/poison damage to it's chompers? Since it has horns I am also giving it a Ram attack! For skills, I am thinking of giving it Acrobatics and performance, since it likes being the center of attention.

Stat wise I'd give it the higher ac, since it has scales and therefore deserves some natural armor. With Wings, it deserves a flight speed but I think making them more of a secondary means of movement seems fair, maybe limiting its flight speed to 15-20 feet rather than a full 30. Finally, I'd slap some dark vision on it and call it a day! What do you think? Stat-wise, I am not too sure though.

For the Ganuthor: This creature seems much larger than the Gallion, so probably medium, maybe even large. Based on its description I would give it the stealth skill to be an expert in (Basically giving it expertise). Beyond that, it's really down to its appearance for us to work with. Obviously it gets a fly speed, a claw attack, and a bit attack. I could see this petpet getting the flyby attribute too! Not sure what else would go into this beat though: it would likely end up being a flying, watered down Tiger/Lion.

Thoughts? Also, don't be afraid to play a revised ranger or use any of the Tasha's optional class abilities! As a ranger player myself I know how it can often feel very underwhelming as a 5e ranger.
