Death of Obsidian Butterflies

When the character releases the magic, her player rolls (Perception + Occult), adding a number of successes equal to the sorcerer's permanent Essence. Everyone in the attack pattern not behind an inch or more of stone or several inches of wood is subject to attack.

Characters defend against Death of Obsidian Butterflies as if it were a hand-to-hand attack. Each attack is independent, so magic and penalties that reduce the attack do not help others defend. Treat the butterflies as rolling a number of attack successes equal to those the sorcerer's player rolled, minus one for each two dice of penalties that circumstances impose. The attack inflicts 8L plus any extra successes in raw (pre-soak) damage.
