Void Stone

Your Transmuters Stone becomes unbound to the realms, and transforms into a Void Stone.  When you cast the spell, choose one of the following options, the effects of which last for the duration of the spell unless otherwise specified.

FORMLESS PRESSENCE:  A creature within range enters a fluidic state.   Choose one type of damage, that creature is resistant to the next attack of that type.   Once used this fluidic state ends.

ABSENSE OF LIGHT:You can use an action to create a sphere of magical darkness(40’ in diameter)to be centered on your Stone.   Whomever is holding said Stone has Devils’s sight for the duration of the spell. 

TETHERED SOUL: A creature within range is bound to you for the duration.   Any healing received by the teathered creature is halved, and you receive temporary hit points up to twice your wizard level, or half of the amount healed.  While teathered both creatures knows where the other is at all times.

GOLEM:  A creature’s skin becomes as hard as bedrock.   For the duration, their AC increases By 2, and their movement speed is reduced by 15.

UNBOUND PRINCIPLES: As an action, YOU can consume your Void Stone to unleash pure alchemy within your body.   Your DM chooses what happens.   Typically the effect has a major benefit, or a minor detriment but there is always a chance for errors.......Consuming more than one Void Stone in this way, or by mixing it with various magical potions can alter the effects further and you are unable to make another Void Stone for at least 10 days.
