Global enchantments

[OmikronWarrior]

Extra gems means the global in question is harder to "dispell". That means actually casting Dispel, and other ways spells get dispelled. If you cast a global when 5 are already up, the game will RANDOMLY pick one to attempt to "dispell", with out regard to how hard or easy it will be to dispell. If the spell selected had a lot of extra gems in it, then chances are it won't be dispelled unless you used extra gems.
