Contest #11 - Datachanging challenge

[Silverthorn]

is it allowed if you create some kind of new char to modify other chars data or is it only allowed to create new dat.-files?

Sounds like a mini-mod. Editing other character's files in order to accomplish your goal (fe. a new effect) isn't really what it's supposed to be. Try to stick to as few edits to other files as possible.

can we update our entries?

Sure, just specify which one you want to enter at the deadline.
