Area 5-foot burst
Range 10 feet
Duration 1 minute
You scatter a cloud of highly explosive magic dust into the air near you that only those who mean you harm can ignite. This dust is hard to see, requiring a [/act seek] roll against your spell DC to identify. You and your allies can pass through it safely, but enemies who move into the dust trigger explosions, taking 1d4 fire damage for every square they pass through. Once the dust in a square explodes, that square becomes safe for everyone. If all the dust explodes, the spell ends.
Heightened (+2) The damage an enemy takes by passing through a square increase by 1d4.
