I'm having some issues implementing my new spells, first the spells does not show up in techs when I have added the "Prereq tech" thingie (they work well, they just don't show up
) I could make items to look like spells I guess? Or is it something stupid I forgot? 
Destiny's Insight flat out refuses to be copied and tampered with, I've tried several new internal names, and it doesn't show up for some reason. Any ideas why?
Lastly I can't get this spell to kill the champion as it is supposed to. Everything else works....
It's almost exactly copied from Steal Spirit.
