Heal Beam is the fifth Tech learned by Robo in Chrono Trigger. Unlike the Cure Beam that Robo starts with, Heal Beam can heal all allies instead of one, and can be used both in menu and in battle.
Animation
Robo begins charging energy, which looks as though he's casting a spell, similar to Marle's Cure in appearance. He then spreads the energy outward from his body in the form of a blue circular wave, which provides light healing to himself and his allies.
