I would like to know if the effects of global spells stack . I know that the visual component of the Global spells do not stack which is for the best because it would be hard to see anything if a few were going at a time. I have search everywhere and can not find an answer to how does multiple Global Spells react to each other or do they cancel each other out. I hate to think that when I use one that I am wasting my pips or my teammates pips and mana. I am amazed that I can not find anyone else wondering this same thing.
