More companions? Same book? A thought on proficiency variant beasts

[Desteplo]

In 3.5 there was a system for familiars and animals that level with you. For druids and rangers you were able to replace with a stronger animal but take penalties on that lvl up system

In 5e it’s just rangers, and the only thing that they lvl off of is your proficiency mod. But what if that’s enough?

What if 1/4 is as normal
1/4 large is -1 proficiency mod
1/2 is -1
1/2 large -2
Etc

I like PHB beast master and that’s what I’m playing around with. I know what they were going for and feel -proficiency blends well (harder to train bigger and stronger beasts)

That or thinking -2 per jump

I want a Swarm of Insects as my companion! lol How creepy would that be?


Anyway, I like idea and would be willing to give it a try for sure.

I’ve actually done something like this already, years back. I rolled back the proficiency once at CR 1/2 and again at CR 2, which kept the numbers consistent across all creature CRs. I’ll see if I can find the notes for it tomorrow.
