This flight mode is fun. It turns the resource collecting chore into a game of Thief.
Some of the ores are guarded, but sometimes she is able to fly in at a certain angle and quick-steal the porcelume ore before the opponent is aggro'd,
and then she can fly away like a phantom thief in the night.

Much faster lumite farming.
