Prototype Amber

HP Catalyst with Burst-triggered party healing and Energy restoration

Released Sep 28, 2020

Prototype Amber is a four-star Catalyst with an HP secondary stat. Using an Elemental Burst starts a six-second effect that periodically restores Energy to the wielder and HP to all party members. Consider it when the wielder can use a Burst and the party benefits from this timed healing and Energy recovery.

Understand Prototype Amber

Useful when…

  • Restore HP to all party members over the six seconds after the wielder uses a Burst.
  • Restore Energy to the wielder during the same Burst-triggered period.

Burst effect

At Rank 1, using an Elemental Burst starts a six-second effect. Every two seconds during that duration, the wielder regenerates 4 Energy and all party members regenerate HP equal to 4% of their respective Max HP. At Rank 5, the corresponding amounts are 6 Energy and 6% HP every two seconds. The weapon has 42.401 base ATK and an HP secondary stat. The periodic recovery requires a Burst to start the effect.

Practical support

This is a Catalyst option for adding party-wide healing and personal Energy recovery to a Burst use. The listed healing is expressed as a percentage of Max HP, while the Energy amount is a flat number for the wielder at each two-second interval. It does not state an attack-hit trigger, shield condition, or damage bonus. Consider its support value alongside the wielder’s ability to use the Burst that activates it.

Ascension and refinement

Ascension progresses from stage 0 through 6; the supplied cost examples cover stages 0→1, 3→4, and 5→6. Refinement increases the Energy and HP restored at each two-second interval, from 4 and 4% at Rank 1 to 6 and 6% at Rank 5. Refinement consumes a duplicate copy per step. Ascension is the basic weapon progression; refinement is useful if stronger Burst-triggered recovery justifies those copies.

Alternatives and limits

A Thousand Floating Dreams focuses on Elemental Mastery and elemental-type-based party effects. Angelos’ Heptades grants ATK and timed damage support and Energy restoration when its wielder creates a shield, with its own shield condition. Apprentice’s Notes is a basic one-star Catalyst with no listed secondary stat. These comparisons do not provide Prototype Amber’s listed Burst-triggered party healing, and each has a different stat or trigger.

Limitations and tradeoffs

  • The recovery effect starts only when the wielder uses an Elemental Burst.
  • Energy restoration is for the wielder; HP recovery applies to all party members.
  • Refinement consumes duplicate copies.

Common mistakes to avoid

  • Expecting the periodic recovery without first using an Elemental Burst.
  • Treating the Energy amount as party-wide; the described Energy restoration is for the wielder.
  • Confusing each two-second recovery interval with the entire six-second effect.
