Homing lasers

You dash back and launch a volley of homing lasers. "Dodge that," you yell in her direction. Zafra doesn't dodge the lasers, instead she simply brings up a Mummyhead shield and accepts the attack with indifference. Before the last of them fizzle out on her shield, you charge a burst shot and throw it at her. That should hit even through the Mummyhead. You've got her!

Zafra drops the shield and puts up her Frame's own guard, a shimmering plane which your shot rolls along. It flies away having done no damage. This is getting frustrating...!
