boiiiiii

Very good

How do I add this beast to my Ranger Character sheet on D&D Beyond, so I have the attack & skills information available during an adventure using my iPad? Thanks for your time. 

You can write down the info in your "Other Possessions" tab or just copy the link there. Unfortunately, there is no native support including him straight into your page.

Thanks for the idea.

The fact that the panther does not have Darkvision is quite odd.  IRL, all cats big and small are night hunters and as such have superior night vision, several times better than that of humans (whereas dogs and other canines have roughly the same or only slightly better night vision than humans).  It’s funny that the tiger has Darkvision but neither the panther, lion nor the cat do. At my table, all cats have Darkvision and I’m also considering whether to give them advantage on Perception checks involving both smell and sight (to match the canines’ advantage on hearing and smell).

i am a dark elf archer,ranger and get a pet, she is a panther and her name is amber

@Sash_Uilos I was actually going to mention this so I'm glad you brought this up already, although I didn't realize darkvision was lacking from the lion and cat as well.

AKA the puma, cougar, mountain lion. A panther can also refer to the Panthera genus, which includes lions, tigers, leopards and jaguars, while black panther refers to black furred leopards and jaguars.  
For a Jaguar, black or otherwise, I would increase the CON to 12, Health to 15, and increase the damage dice to 1d8 and 1d6. Just enough to establish it's not something your average human is going to want to fight.

Cats can't see in total darkness, they have low light vision, so only the first benefit of Darkvision applies.  Since there is no in-between for Darkvision and normal vision anymore, as there were in previous editions, they opted not to give them the ability to see in total darkness.
As a DM, I would allow them to have limited Darkvision, but I assume this isn't something they wanted to define in the rule books.

On the Pounce ability, is the bonus action dependant on the ability itself being used or can the bonus attack be used if someone is already prone and adjacent to the panther (like the panther starts the round adjacent to the prone figure)? Just something that my group was trying to clarify.

I feel like it could be left up to the DM's discretion. But my interpretation of the ability is that the panther gets the bonus action because it knocked the creature prone, hence the need for a saving throw. So if it was prone for any other reason, I dont think the panther would get the bonus action. Again though, I feel it could be left up to the DM to decide. 

Anybody want to get creative and make me a cat that can shape shift into a panther. I'm too lazy.

It's really weird that a panther or tiger etc. are just "Medium". I know in terms of length they fit the size, but if you use miniatures they'll look too tiny on the board.
One square "kitty". So I tend to make them "large", since they are longer and usually heavier than your average humanoid.

!!!

go on your character sheet, extra (near actions, spells, equipment etc)- add extra-  scroll down list- selected beastmaster companion- FInd panther in the list.

Enjoy!

Thanks.

Oh golly, thank you so much!! I never would have found this feature on my own!

Find it funny the Panther doesn't have Darkvision like it does in real life lol
