Since the Resonator is highly important for Echo Release, it is recommended to prioritize leveling up skills with Echo Release.
After Echo Release, it is recommended to level up Echo Skills second to further increase the party's healing!
Echo Release > Echo Skill > Forte Skill = Echo Circuit > Basic Attack
Sentinel's Echo Circuit is an attack-related skill with an attack power coefficient, not related to healing & buffs.
Therefore, it is recommended to level up Echo Release and Echo Skills first to increase healing.
📌From level 7, where the material consumption increases rapidly, it is recommended to increase Echo Release and Echo Skills by 1 each.
ex.Echo Release 7 → Echo Skill 7 → Echo Release 8 → Echo Skill 8 → Echo Release 9 → Echo Skill 9 → Echo Release 10 → Echo Skill 10
It is recommended to level up Echo Release, Echo Skill, Echo Circuit or Forte Skill to level 10 in that order.
If you lack resources for a long time around level 9-10 for both Echo Release/Echo Skill, you can allocate to Echo Circuit or Forte Skill.
Since Sentinel is a supporter, the proportion of basic attacks is low, so it is recommended to invest in it last.
