Sky Sovereign Phaleon Caelus Wind

Max rarity ★5, 3 evolution forms. Skills and Lv99 stats are listed for each form.

Base: Phaleon Skyrider (★4)

Active skill: Aegis WallDamage taken −60% for 5 drops ／ Target: shared party HP (effectively whole party) ／ Stacking: protects the whole party's HP. Percentage damage cuts do NOT add up between active skills — only the single highest applies (duration keeps the longest). They still add with leader damage reduction.
Trigger: Triggers when HP ≤ 70%
Cooldown: 37 drops initially, down to 25 drops (Rechargeable)
Leader skill: Balanced ChampionDamage on merges with no element advantage 1.7× ／ Combining: when the leader and sub-leader share the same effect, their multipliers multiply together. They also multiply with an active skill's damage multiplier (only the single highest one if several are active at once)
Lv99 stats: HP 5324 ATK 585 Heal 178

Active skill: Aegis PrayerCleanse all status + shield next hit ／ Target: shared party HP (effectively whole party) ／ Stacking: protects the whole party's HP. Same-type defenses stack separately. Some defenses only work when the enemy telegraphs an attack
Trigger: Triggers when HP ≤ 60%
Cooldown: 33 drops initially, down to 22 drops (Rechargeable)
Leader skill: Balanced ChampionDamage on merges with no element advantage 1.7× ／ Combining: when the leader and sub-leader share the same effect, their multipliers multiply together.

Lv99 stats: HP 8518 ATK 878 Heal 267

Active skill: Skyward AegisHeal 60% max HP. For the next 6 drops you're in an "overheal" state: overflow from any heal (heart jewels, other heal skills) banks into a barrier up to 2× max HP. The barrier doesn't expire over time — it absorbs damage before your HP until depleted ／ Target: shared party HP (effectively whole party) ／ Stacking: healing stacks. While in the overheal window, anything past max HP banks into a barrier that doesn't expire over time — it takes damage before your HP until depleted
Trigger: Triggers when HP ≤ 50%
Cooldown: 22 drops initially, down to 15 drops (Rechargeable)
Leader skill: Tempest InsightWind ATK 2× + 4+ chain damage 1.6× ／ Combining: an always-on effect. Both the leader and sub-leader apply at the same time
