or to actually make them fear dead.I didn't read all this, but i think the main point about a punishment would be to stop people from going to the cross resurecting, and then attack the one who killed them once again. This can not be too hard to acomplish...
Samantha told Aeridor he will die if he doesnt stop being impudent. he continued, evemn after she casted a warning spell on him. he knew what will happen and ignored it. he than got flamed. 15 seconds later he came back from cross, and continued right where he stopped, mocking her on the same way.
Such behaviour is not better than comming back from cross and attacking again. such behaviour shows the lack of any fear of death, or even taking death something terrible.
