Here's what you need.
-Reflecting Prism(really easy to get)
-a friend (druid would be nice)
-toys to transform you
I haven't seen this before sooo,
Have your friend transform to what you want to become. This ranges from the snowman kit, brazier of the dancing flame, druid transformations (fight as swimming orca), all the way to ancient's bloom. Then you use the Reflecting Prism on him. Now you are what he is, without moving restrictions or fighting.
