feedback on my homebrew item

i make an item to be able to store tamed creatures so my character can be the best beastmaster in my campaign while not having hordes of creatures following the party around. my dm said they would be open to look at it and think about it so i would appreciate some feedback. (i used an ai to help with formatting but was too tired to re-read everything so if there are any mistakes or problems just let me know so i can fix it)

So, it's essentially a pokéball?

You can use an Action to touch the sphere to a tame, non-humanoid creature.

"Non-humanoid" is a very broad term. If the idea is to have the character to be a beastmaster, why not limit the creature type to Beast? And what is considered tame? For example, a guard dog might be tame, but it could very well be hostile towards you if you're not the owner. Given their low intelligence score and the fact they're tame, means that you can force one into your pokéball and now you have a hostile dog with you. I would rephrase this that the beast needs to be friendly towards you.

Capacity: Up to two creatures of the same species (Small, Medium, or Large). If a creature is Huge, the sphere can only hold one. It cannot hold Gargantuan creatures.

You're already specifying one huge or two large or smaller. I find explicitly saying "cannot hold gargantuan creatures" redundant.

Once a creature is released during combat, it cannot return to the sphere for 5 rounds (30 seconds).

Why? I understand this mechanically, but why? What if the creature is released outside of combat? Can they then return whenever they want? Also, everyone knows how long 5 rounds last. I would specify only the time and remove the "during combat". Then it's clear it means always.

Does a creature inside the sphere need eat, sleep, or breathe? Can a tamed creature die of suffocation or undernourishment?
