"Good idea. All of you, disperse!" she says to the others, and then takes the remote detonator from Peridot. She's not concerned about herself after all. "I'll take it from here."

The Ringmaster will wait for the other supervisors to get out of the way before raising her arms theatrically. The trees around the sigil grow and twist and spin together, creating a shield of wood between the blast area and everything else, leaves spiraling up into the sky. She puts a hand on her hip, satisfied with her work, and then looks at the detonator.

"Boom," she says, and presses the button.

It is quite loud.

The trees shudder and crack from the force of the blast, and once ground zero moment has passed, small chunks of wood will rain from the sky for a while. The Ringmaster will step through the rubble of burnt trees, waving away smoke with a gust of wind onto to see the sigil still there - its lines now burning like embers on the blackened ground. The torn earth means nothing - the sigil is burned straight through the dirt, who knows how deep.

"Well... Worth a shot," she says, climbing back out over the smoldering wood.
