Echo - Phantom: Rock Guardian

Use the Echo skill to transform into the Rocksteady Guardian. You can defend for a period of time. After being attacked, you will directly inflict a Spectro damage based on the current Character's maximum HP 5.18%, and perform a follow-up attack to inflict a Spectro damage based on the maximum HP 5.18%. During the transformation, you can use the Echo skill again to exit the transformation. If the attack received is a special skill attack, it will break the enemy's special skill and perform a two-stage follow-up attack, each stage inflicting Spectro damage based on the current Character's maximum HP 3.45%, and simultaneously launching three ground-breaking waves, each inflicting Spectro damage based on the maximum HP 2.87%.
Skill cooldown: 15 seconds.
