Recover and sustain

For flat healing skills, start with C = (base + per-rank × rank) × mastery/synergy. The default scale is round(C × rate × sqrt(max(210, damage base))), with rate 0.0097 for party healing and 0.0199 for self healing. Damage base is the five direct channels summed, not attack DPS. A percent-of-max-health skill follows its relative formula instead.

An instant skill then multiplies the normalized amount by its base cooldown in seconds. A HoT divides by its base uptime to obtain the active per-second amount. These normalization steps are part of skill magnitude; changing cooldown does not rewrite the base coefficient.

Skill heal offered = base skill heal × (1 + Heal Power / 10,000) × (1 + Heal Received / 10,000). Positive runtime caps are applied if configured; shipped defaults have neither positive cap. Actual healing = min(offered heal, missing HP), subject to encounter healing restrictions.

Case: 1,000 base heal, +20% Heal Power, +30% Heal Received. Offered heal = 1,000 × 1.2 × 1.3 = 1,560. A hero missing 400 HP receives only 400. Overhealing does not become extra maximum HP by default. Entering Heal Power in a skill preview and multiplying it again would double-count the same modifier.

Timed HoT ticks immediately on attachment and once per second before expiry, using the recipient’s Healing Received. A 100-per-second HoT lasting 6 seconds has six potential ticks at 0–5 seconds. At +30% Healing Received it can offer 780 total, but every tick is capped by missing HP at that moment.

Final Regen heals on the combat engine’s global one-second tick, using the normal actual-heal limiter. The raw character build applies a ×1.5 scale; do not apply it again to an already-final displayed value. Regen does not pass through the skill Healing Done/Received function. The native Priest stat construction also adds floor(Attack × 0.15) to raw Regen before final scaling.

Lifesteal = resolved positive damage × rating / 10,000, then actual-heal limits. It uses the damage passed to its event handler, not an expected DPS number. True DoT and Thorns can also invoke this handler. This path does not apply skill Heal Power/Heal Received.

Case: a resolved 800-damage hit with 5% Lifesteal. It offers 40 HP. Adding +20% Heal Power does not turn this particular Lifesteal call into 48. A boss shield/phase or a special encounter heal budget may change the damage or healing actually credited.

The engine can apply a combat healing multiplier and a boss sustain allowance based on boss damage taken. Those are encounter-specific. A heal formula alone cannot guarantee that a hero survives a particular Colossus hunt.
