I want to weld Player joints

  1. What do you want to achieve?
    I want to make a throwable potion that turns the player into a stone, basically once you are hit you cant move and can fall over, as if you were an unanchored welded statue
  2. What is the issue?
    Im not sure what i should use to turn the player into stone, i tried welding the motor6d’s but that didnt work, the throwing itself isnt a problem
  3. What solutions have you tried so far?
    I have tried using RigidConstraints and WeldConstraints but they dont work, RigidConstraints does the job but the player turns into a ragdoll, i want the current pose to stay

all i need is to know what should i use to make this weapon of mine.

I believe you can use rigid constraints you just need the the attachments to be set towards the pose via the Motor6D transform data.

--Attachments of the rigidConstraint
attachment0.CFrame = motor6D.C0*motor6D.Transform
attachment1.CFrame = motor6D.C1
