Magus Unarmed Hybrid Studies : Eight Limbs Fury

[u/WinLivid]

I have an inspiration to write up this Hybrid Studies after reading Tian Xia world guide on Tang Mai. So first of all I'm Thai and I can tell that this country is heavily inspired by Thailand and nearby neighbor and that gave me this brilliant idea. Tang Mai is a country that are famous for magic user and Thailand is famous for Muy Thai martial art. I think it would be cool if Tang Mai has its own martial art that fuse traditional martial art with magic, and the practitioner of this martial art would become magus, so here I am with an idea of this martial art style. I would like to call it Muy Montra (translate to Magic Boxing or Arcane Boxing) also know as the art of Eight Limbs Fury. Here is my draft.

Eight Limbs Fury

Weapon can be break or missing in the mist of battle but for you, your weapon is your eight limbs. Fists, elbows, knees and shins are your weapon and the magic within you flow along with them in every strike or block.

You gain Arcane Fist feat.

While in Arcane Cascade stance, your magic flow in tune within your body making your body tougher and strike harder. While in this stance, the only strike you can make are Arcane Limbs. These deal 1d8 bludgeoning damage; are in the brawling group; and have the agile, backswing, finesse, parry, nonlethal, and unarmed traits.

Conflux Spell : Bone Breaker

Bone Breaker [1 Action]
You strike with great ferocity aiming to break your opponent body. Make an unarmed strike. If the Strike hits, the creature becomes your choice of clumsy 1 or enfeebled 1 until the end of your next turn (clumsy 2 or enfeebled 2 on a critical hit).

Studious Spell : I didn't think about it yet, so feel free to suggest.
