Make the robot a Buddhist. Every time the robot defeats an enemy have some platitude be expressed (Be witty and varied). Use alternative strategies to avoid combat where possible which increases your enlightenment level which unlocks new abilities such as "Befriend - an enemy becomes your ally", "flower power" - an area of effect which obscures enemy sight, "12 step program" - your robot creates 12 invisible steps usable only by them by which they can climb up 12 steps. The boss has one hit point at the end and is immune to "befriend" - your goal is too avoid all of his attacks whilst preaching many, many pithy sayings that over time increase your enlightenment level until you achieve full acceptance and then die to evolve onto the next level. If you kill the boss you restart the entire level as you have obviously not advanced enough to ascend beyond this level.
