With the Executors boxing her in, there's only one direction for Rei to go – backwards! She leaps back and away from the Executors, taking herself out of their immediate range.

As she goes, though, Rei brings down her sword to skim the surface of the lake. This causes the surface of the water to freeze, becoming a hazard – it's both slippery and brittle, putting you at risk of slipping or stepping right through the ice and becoming stuck.

Because of the hazard, Lion and Obstacle lose one Movement for the following turn. La Luna is unaffected.
