MM24 cr0 Familiars of note
Now that familiars can be any cr0 beast, and the MM24 is out, we have some interesting new contenders for interesting familiar options.
Most interesting to me: mounts for small creatures
Deer - Medium 50 ft move speed and "*Agile****.*** The deer doesn’t provoke an [Opportunity Attack](https://www.dndbeyond.com/sources/dnd/free-rules/rules-glossary#OpportunityAttack) when it moves out of an enemy’s reach" So when the deer leaves and brings the rider, neither get aoo'd.
Goat - Medium with a 30 ft climb
Vultures - Medium 50 fly speed - must make the argument that your characters total weight is under (15\*7) 105 pounds. Also no hover speed, so if something knocks them prone they're grounded.
Shout out to baboons for having hands, being small and 8 str and 14 dex. Using Rope to restrain a creature is a dc 10 check (if they're grappled, incapacitated or restrained) and a dc 20 to bust out.
For seeing invis: Find Familiar lets casters use a bonus action to see through the eyes of their summons and also gain the special senses. So shout out to the blindsense crew (specifically negates invisibility) - Bats with 60 ft blindsight, crabs and glow beetless with 30f blindsight
Are mounts great combat options? Not with those hp. But I am so unlikely as a player to buy a mount from town that this has some serious flavor appeal.
