Your friend and you teamed up to fight a "magic boss." You were responsible for using "shield magic" to defend, while he used "lightning magic" to deal damage. However, he was too fast, and the lightning struck your shield, which you hadn't retracted in time. The shield instantly turned into a "conductive plate," shocking your character and making you bounce around. In the moment the boss was stunned, you managed to take away half of its health.
