As far as I can tell all roots have this -10000 value writen in MIN effect field , and all roots relatively easy to break with nukes.
Perhaps we can add some extra code to the server which would treat this property of "10000" as a modifier to chance of root breaking, so then If I would to create a Custom Root spell and put 20000 in that value instead it woudl make root twice as hard to break before it expires, or 100,000 - 10 times as hard to break and so on.
Or perhaps use a MAX effect field (curently 0 for all roots) to describe a modifier such as 2, 3, 4, 10 etc (as bonus to root durability)
how about it?
