You haven't really comprehended anything I've been saying since you first started posting, you can continue to obfuscate all you want as this will probably be my final reply to you. I am not interested in your opinion anymore. Variant human and human do not have the same ability scores so that is a false equivalency. Returning to the main point, the stat block speaks for itself.
"Variant: Familiar: The quasit can serve another creature as a familiar, forming a Telepathic Bond with its willing master. While the two are bonded, the master can sense what the quasit senses as long as they are within 1 mile of each other. While the quasit is within 10 feet of its master, the master shares the quasit's Magic Resistance trait. At any time and for any reason, the quasit can end its service as a familiar, ending the Telepathic Bond."
Why would WOTC include this if it was to just be ignored? That is really confusing.
This is from the subclass
"You learn the Find Familiar spell and can cast it as a ritual. The spell doesn’t count against your number of Spells known.
When you cast the spell, you can choose one of the normal forms for your familiar or one of the following Special forms: imp, Pseudodragon, Quasit, or Sprite.
Additionally, when you take the Attack action, you can forgo one of your own attacks to allow your familiar to make one Attack of its own with its reaction."
So......maybe you don't agree with me, but I certainly am not making things up. Good day to you.
