New attribute “Regen. Bonus” – a regeneration healing modifier

Regen. Bonus – the new Life-Recovery attribute in Legendary Season (Patch 2.8.8)

Introduction: why this stat matters now

With patch 2.8.8 and the arrival of Mythic-quality Legendary Equipment, Infinity Kingdom introduced a modifier that fundamentally changes how survivability can be built on the player side: Regen. Bonus. This is something entirely new – at least as something available frontend to players – and as such it deserves our time. Let’s dive in and see what this is and what possible changes and implications this new attribute may have.

Unlike most attributes we are accustomed to, Regen. Bonus does not increase damage, reduce damage, or amplify outgoing effects. Instead, it directly improves how efficiently an Immortal converts healing into HP. Given the clear direction toward longer fights and sustain-heavy gameplay in Legendary Season, this is one of the most strategically important stats added in recent years.

Reframing the attribute system (with an important clarification)

To understand why Regen. Bonus is so distinct, we need to look carefully at what our existing attributes do.

Core attributes and derived effects

Every Immortal has base values derived from these systems:

  • Strength
    • Physical Attack: Increases physical damage dealt
    • Physical Defense: Decreases physical damage taken
  • Agility
    • Crit: Increases chance to crit
    • Dodge: Decreases chance to be hit
  • Intelligence
    • Magic Attack: Increases magic damage dealt
    • Magic Defense: Decreases magic damage taken
  • Physique
    • Accuracy: Increases chance to hit with physical attacks
    • Resilience: Decreases chance to receive a critical hit
  • Magical Penetration
    • Increases magic damage relative to enemy Magical Protection
  • Magical Protection
    • Decreases magic damage relative to enemy Magical Penetration

These attributes define combat throughput and mitigation. Sustain, however, has always been more opaque.

Aptitude: long-standing assumptions vs tested reality

Aptitude deserves special attention here, because it highlights why Regen. Bonus is such a meaningful addition.

For years, many players believed Aptitude affected:

  • Healing values
  • Shield strength
  • Or both

An IK VIP representative has confirmed that Aptitude does modify shield values, but does not modify healing. Even with that statement, the mechanic has remained difficult to verify conclusively in practice.

From player-side testing – including my own – Aptitude does appear to influence shield strength in measurable ways. However, across repeated testing cycles, I have not found consistent evidence that Aptitude meaningfully affects raw healing received or healing output.

This uncertainty is important, because it means that prior to Legendary Season, players had no reliable, itemized way to scale healing received. Regen. Bonus changes that.

What Regen. Bonus actually does

According to clarification from the Infinity Kingdom team, Regen. Bonus or Regeneration Bonus as I think it is short hand for, is an attribute which is:

“For HP, more specifically Life recovery.”

Mechanically:

  • Regen. Bonus increases healing received by the Immortal
  • It applies after the heal value is calculated
  • It does not affect energy gain, rage, or skill cooldowns

This makes it a target-side sustain modifier, which is something the attribute system previously lacked.

Practical example: healing amplification on the recipient

Consider a common sustain scenario.

If Zenobia heals a frontline Immortal:

  • Zenobia’s skill calculates its heal normally
  • Regen. Bonus on the target increases the final recovered HP
  • The effect stacks with all other sustain mechanics

This is distinct from healer-side bonuses and avoids the ambiguity that has always surrounded Aptitude and healing interactions.

Roll values and constraints

Regen. Bonus appears exclusively as a Mythic equipment modifier:

  • Minimum roll: 0.30%
  • Maximum roll: 3.00%
  • Type: Percentage-based
  • Source: Mythic reforging and rerolling

While 3% looks small in isolation, it is applied every time healing occurs. In extended Legendary Season combat, the cumulative effect is substantial.

Why Regen. Bonus aligns with the evolving meta

Legendary Season is already defined by:

  • Higher level caps and HP pools
  • Lower relative burst outside select immortals
  • Longer PvE and PvP engagements

Upcoming systems reinforce this direction. Once Divine Blessing goes live, overall damage is expected to drop significantly for most immortals, with Medusa remaining one of the few consistent damage outliers (her damage being a Passive effect it is supposedly not affected by Divine Blessing, hence the new tier to whale meta…). Anyway, for most of us what is important here is, that once Divine Blessing becomes a thing, we are likely going to see more sustain, ramp-up and prolong centered builds being favoured in the meta. That means healing values become highly relevant and this new attribute is an important piece of the puzzle to know about!

Historically, whenever damage compresses in Infinity Kingdom, the meta shifts toward:

  • Sustain cores
  • Ramp-up damage dealers
  • Healing efficiency over burst mitigation

Regen. Bonus fits this environment perfectly. It rewards time, positioning, and repeated healing rather than one-off shields or damage spikes.

Strategic implications for Mythic equipment

  • Regen. Bonus is strongest on immortals expected to be healed repeatedly
  • It scales with fight length rather than damage windows
  • It complements sustain comps better than shield-only setups
  • It benefits PvE, Elemental Domain bosses, and drawn-out PvP

Because Mythic equipment is permanently bound, Regen. Bonus is best treated as a long-term identity stat for frontline anchors or sustain carries.

Conclusion: a sustain stat we’ve never truly had before

Aptitude hinted at sustain scaling but never delivered clarity. Shields were affected, healing remained questionable. Regen. Bonus is the first time Infinity Kingdom has given players a clear, testable, and controllable way to scale healing received.

In a Legendary Season meta moving steadily toward slower combat and layered sustain, Regen. Bonus is not just another modifier—it is a signal of where the game is heading.
