Alright, so with the help of Le Pug and Touched, I've made a very, very ratchet system for it. The repel's effect wore off script offset is at 2A4B2A, so you can repoint it or just goto [MENTION=17182]pointer[/MENTION] it...
Anyways, of course, this would be much better with a multichoice, but just for testing I did yes/no boxes. Anyways, here it is, you don't need to credit us or anything..
