Diamonds 
Support 
Arcane Meret is a Stars-faction Note-based support who distributes Sun, Moon, and Star Notes to key allies at battle start. Notes provide shields, attack buffs, and energy — and with Harmony of All Things, Note-bearers share damage with each other, creating a distributed damage pool. Her Artifact makes Note-bearers unkillable once, and her heals prioritize the weakest ally. Exceptional at keeping high-value units alive and amplifying their output simultaneously.
Diamond Support with protective life-sharing mechanics. Shields Heracles during ramp-up phase but can slow his energy recovery -- known tradeoff. Insufficient against high enemy burst. r1-10 enough for baseline utility; r30 for full protective output.
Passive: Upon entering battle, Meret distributes three Notes - Sun Note to the ally with the highest Max HP, Moon Note to the ally with the highest ATK, and Star Note to herself. Active: Activates all Notes. Sun grants a shield equal to 30% of Max HP. Moon grants +30% ATK for 8 seconds. Star restores 200 Energy.
Marked allies share damage taken. The main target takes 60% of incoming damage, and the remaining 40% is split among other Note holders. Additional effects: Sun grants +10% Max HP, Moon grants +20% damage dealt, Star grants +10% Energy regeneration.
Heals the most vulnerable ally, restoring HP equal to 60% of ATK per second for 5 seconds.
Passively, when an ally drops below 50% HP, Meret heals them for 25% of their Max HP. Can trigger once per unit.
When a Note-bearing ally would die, prevents their death and grants them a shield equal to 300% of ATK. 15-second cooldown.

Baseline protection unlocked. Usable in Diamond team without further investment pressure.
Full protective capability. Only relevant once Hercules and Bastet are already at Divine.
Baseline utility at r1-10. Full potential only realized at r30, and only if paired with high-investment Hercules and Bastet. Not a priority for F2P players until those conditions are met.
