[Solved] Negative values

[Miikey]

May sound stupid, dumb... again stupid and dumb, but how do I give negative values to the integers of my spells??
E.G: The Item armor bonus( Item Spell), how can I give it negative armor Bonus?? Can;t drop it below 0.

Fire -> Preferences, tick "Enable negative values". Now Shift + click given field, and customize as you desire.
