object that fades after the summoner dead

[~Dome~]

you can use the move after death technique.
If the character dies, it will activate a frame with an itr/state: 3005 which will destroy the object if I remember correctly.
You have to use some unusal bdys for the object and itrs for the state: 3005 frame. some that dont interrupt the battlefield, for example a wide area under the ground. [x: -1000 y: 1000 w: 2000 h: 1000 or something like that]
