If you chaincast your snowballs people get mad at you.
I usually chaincast my snowballs in wars, so I can hit them with as many as possible.
In groups you can throw hard-packed snowballs which will pop invis, take out your Food/Drink Tic, ect. They also do damage (1-2) and shoot from farther distances.
Yes they are very fun.
Heh, I enjoy standing in buildings and throwing them so no one konws who did it.
