The reason Soran didn't advance too far into the grassy field was due to the darkness of the night that would hinder his fight against the monsters. But it didn't mean that this was the worst situation. He could use the light from his katana skill as a source of illumination – oh, and of course, it wasn't as simple as it sounded.
Skills would temporarily provide a light effect to weapons, including a person's body depending on the skill type, but the effect was only temporary. While Soran could spam the skill to have ambient lighting around him, that wouldn't be a wise course of action.
