I was reading "Professor Q's Guide to the Controller" recently, and was quite surprised to see that he rated Elemental Evil's 2nd level spell 'Skywrite' as one of the few gold options only available to a wizard or druid. The spell itself is a ritual which can be used to write a message in clouds across the sky of up to 10 words which has a range of sight. Apart from spamming advertisements across the sky, or labeling town leaders as a bunch of dolts, can anyone else think of any interesting ways or situations in which this spell can be used creatively?
