Transformations are yet another way of abnormal status displayed by player characters after certain ingame events or conditions, such as a Transform Skill casting, attaching a talisman to your bracelet or finding a cursed weapon .
In normal conditions, skills casting, cursed weapons pick up or some other events will determine whether a certain character must appear in its normal or transformed shape.
From the transforms menu you can enforce any transformation on a selected target, and optionally specify a delay in seconds.
Keep in mind that models may get bugged after consecutive transformations. Clean them up either by issuing //untrasform or pressing the Send button with no parameters, whenever needed.
(sorry, but it seems client gfx weren't meant to allow free and intensive transform cycles)
Have Fun!
