Needs to be smarter! 

Needs to be big brain.

It seems that in some applications of the stats in D&D 5e intelligence is more how much you've read (or learnt otherwise) rather than any qualifier of problem solving skills. The octopus' wisdom would reflect its tool using and problem solving skills.History and religion skills as well as how languages work support this, but the wisdom tilted stats of dinosaurs and many claims about what the stats are in official sources complicate this. Whether charisma is personability or a sort of force of will (for overcoming certain types possesion for one) is another interesting one.

 Raven's and owls are also problematic in this respect.

Maybe the low Int is purely a standardisation so that there don't have to be special rules ensuring that the octopus can't speak despite its Intelligence score being high enough.

 Thri-keen are "sentient" and cannot talk. cephalapods also can "speak" but not in the conventional way we think of, they use color patterns and very simple sign language, they have even been taught to wave as an action that humans understand.

I get the mechanical reasons that does explain it. But there has to be some way for the game to give it the intelligence it deserves.  Scientists know for a fact that they have an intelligence similar to an 8-10-year-old child. That would give it the same intelligence as the early edition orcs. 

They can't talk in real life because their intelligence evolved around a solitary lifestyle. Something scientists thought would be impossible because our intelligence evolved alongside social interactions. Yet this strange creature can solve complex problems and even hold grudges against people they recognize for years. They do all that without living in societies or having parents teach them. 

They could evolve to be just as intelligent as humans, though, with their minds being built differently from the ground up. We probably wouldn't recognize what they become... ok that was a bit more bloodborne than D&D, but it is still valid. They even go through this unique form of RNA evolution that lets them evolve much faster than we can so they could gain-level intelligence much faster than we did. 

 I'm a fan of the idea of modifying them to live longer and be social as opposed to solitary. They would need guidance though so they didn't have to go through a stone age, or end up killing off all of their predators or food sources from the ocean.

I like the ink cloud thing 

Why the crap does it have a 4 Strength? Octopi can snap the spines of sharks and can lift 40 times their body weight. If a halfling commoner has 10 Strength, a Small octopus shouldn't be that far behind. ):(

I’m definitely changing this things intelligence to at least four, squid are smarter them almost any dog, even husky’s and other incredibly smart dogs.

Octopi are the best familiars. You cannot change my mind.

The octopus is a highly intelligent creature. This makes no sense.

I made a warforged powered by an octopus but idk how to do the sidekick levels and stuff

or you could play druid and have shape water plus create or destroy water and use it as a grapple familiar with a dash after each grapple (use the create water spell before a fight bring your octobuddy with you in a bucket or something and then use shape water to throw him to into an enemy allowing him to grapple said enemy, damage him and then get away with its ink dash since it's still submerged in the water you just threw at the enemy), or if you have the create water spell you could use it to create water in an enemies lungs, if your dm allows it that is.  

AAAAAAAAAAAAAAAA AN OCTOPUS

in real life, octopedes can survive out of water for an hour. d&d octopedes are weaker than real ones.

Agreed, I'd put their INT at at least 5 or 6 tbh

Intelligence is the lowest?? Octopuses are crazy smart. 

 true, but 

Quote from RogueShadowDragon >>

If they were based on real world octopuses, they would be OP!

 the game needs balancing man.

bro, freaking balance. if you die and Regen, the doctor that asks for 10,000 $ will go bankrupt.
