Sorry Ive been logged off so long, but im back now that i had time (finally) cant wait for high speed if there are any typos its cause one of my fingers is heavily bandaged . I have question, how do you enter negative values in an ability, for instance if i wanted to make a Devoustion Aura , yet makle it target my enemies and REDUCE armor instead how would i do that? The editor doesnt seem to want  to let me do that. I have a couple other questions  but i cant remember so meh. 

There's an option somewhere under Preferences that you can check to allow negative values for most fields.

Or, failing that, hold shift while double-clicking on a field and it'll let you enter negative values.
