Eagle Marin is a straightforward team healer and one of the most accessible sustain options for new accounts. At max skill, Eagle God's Technique provides full-team healing based on 140% C.ATK, and Mysterious Mask - Awakened gives a guaranteed extra 60% (+Healing) recovery when the skill is used. This creates stable, low-complexity sustain for long fights.
Her basic attack also offers minor self-sustain by converting 80% of damage into HP, helping her survive without heavy protection. She is excellent for early PvE progression and budget comps that need reliable healing without complicated setups. In high-end PvP she is rarely used because modern supports provide stronger tempo, cleanse, or utility, but she remains a very practical beginner healer.
