I want to make a spell that when cast would create an large object to block out all sunlight or moonlight. I was thinking it sould take 2 minutes to take full effect, last 1 minute, and then take 2 minutes to wear off (so its more like a normal eclipse). I was thinking of using a darkness field but it doesnt cause complete darkness. You would still be able to see by artificial light, starlight, and moonlight if this was cast during the day. I want it to have charges but how would I do an inconsistant continuing charge? Should I use Images or Transform instead? If so, how would I make the power?
