All non-flying models in play, including the caster, must resist the spell or be knocked Prone. Each large tree or building in play has a (power) in 6 chance of collapsing as well. Treat collapsed structures as rubble or linear obstacles as appropriate. Any model adjacent to a large tree or adjacent/inside a building takes a Free Hack with a C equal to the spell’s power.
Backfire: Caster is knocked Prone.
