Weave Twist v2

Plucking a strand of hair from your head, you use it as a focus to twist, grind and condense the weave in the space before you and channel it into a projectile, binding and imbuing the object with this spell. 

All of the spell’s effects are lost if you lose concentration.  This enchanted object can be thrown at a creature.  On a successful ranged attack hit, the amassed and spindling weave is released, lashing out in a 20ft sphere/10ft radius.  The spell ends if your body interacts with the sphere.

Fully immersed creatures, up to one size larger than you, that are caught in the ‘weave-tangle’ have their ability to cast magic or maintain a magical effect hindered.  Such creatures must make a contested roll using either their CON saving throw or an Arcana check (D20+Arcana proficiency bonus) equal to or greater than your Arcana check (D20 + Arcana proficiency bonus) immediately and at the beginning of every turn they remain in the sphere.

On a save, the creature is able to use their movement to escape the area on their next turn but cannot be affected by magic and cannot cast spells until they exit the sphere.

On a fail, the sphere's center of gravity is reset onto the creature.  It cannot cast spells, cannot be affected by spells cast upon them while within the sphere, and cannot maintain concentration while any part of their body touches the sphere.

Creatures up to one size larger than you that are touching, but not fully immersed in the sphere OR that leave the sphere: must make a CON saving throw or an Arcana check (D20+Arcana proficiency bonus) equal to or greater than your Arcana check (D20 + Arcana proficiency bonus) in order to successfully interact with magic until the beginning of their next turn.

On a save, the full effect of the Weave Twist on this creature ends or never takes effect.

On a fail, the creature must make all magic related rolls with disadvantage and cannot be affected by magical effects emanating from themselves until the beginning of their next turn, however; they can now be normally affected by outside spells.
