I don't want to make things more complicated but I have a question to ask.
Let's say I use a fireball spell 4/3/1. As soon as the fire ball leaves my hand, the law of nature will take over. The fire ball won't be able to last over a second since there isn't enough oxygen focused around to sustain the ball. Shouldn't the duration be at least 2 instead of 1? 1 should be like a lighting bolt spell.
1 does
not mean "a fraction of a second". It means "a short moment". That can be a couple seconds, so fireball is fine.
