Green archers shoot arrows that can be reflected at enemies to kill them. Red archers shoot bouncy arrows that require a couple of reflections to break, don't hurt friendlies, and if not destroyed, slowly fade away. Blue archers are like red archers, but their arrows start slow, before quickly becoming very fast, and need 2 deflections to break. Red/Blue archers are able to fire red and blue arrows at the same time. Orange archers shoot arrows that can go past your sword.
