Formula used

Direct coefficient = adjusted cast time / 3.5.

Heal over time coefficient = duration / 15.

Area coefficient = direct coefficient × 0.5.

Final coefficient = base coefficient × level penalty × manual coefficient percent.

Bonus healing = healing power × final coefficient.

Expected heal = normal heal × [1 + crit chance × (crit multiplier - 1)].

Effective heal = expected heal × (1 - overheal percent).

Healing per mana = effective total healing / mana cost.

How to use this calculator

Enter the spell name, rank, base heal range, healing power, and mana cost.

Select the spell type. Use automatic coefficients for common estimates.

Use custom coefficient mode when your spell has a known exception.

Add crit chance, talents, overheal, targets, casts, and fight length.

Press the calculate button. The result appears below the header and above the form.

Use CSV for spreadsheet records. Use PDF for quick sharing or raid notes.

WoW Classic Healing Power Guide

Healing power changes how each spell rank performs. It does not add the full item value to every cast. Each spell receives a coefficient. That coefficient decides how much bonus healing is added. Long direct heals usually gain more value. Fast heals gain less value. Heal over time spells spread their bonus across ticks. Area healing may receive a smaller share.

Why Coefficients Matter

A healer often chooses between speed, mana, and safety. A larger rank may heal more, but it can waste mana. A lower rank can be efficient when incoming damage is steady. This calculator helps compare those choices. It estimates normal healing, expected crit value, effective healing, and mana return. It also shows overheal loss. That number matters because wasted healing gives no benefit.

Downranking and Spell Value

Classic players often downrank to save mana. The best rank is not always the highest rank. It depends on gear, talents, target damage, and encounter length. A spell learned at a lower level may need a penalty. The tool includes a level penalty switch and a manual penalty field. This lets you test special ranks or private server data. You can also enter a custom coefficient when a spell has unusual behavior.

Using Results in Raids

Use the result as a planning guide. It is not a perfect combat log replacement. Boss mechanics, latency, resist events, movement, and missed casts can change real output. Enter your healing power from gear first. Then add talents and buffs. Choose the spell type. Add crit chance, mana cost, overheal, targets, and casts. Compare healing per mana and fight HPS. Repeat with another rank. The better rank is usually the one that meets damage needs while wasting the least mana.

Practical Tips

Build a small table for common spells. Include Flash Heal, Greater Heal, Healing Touch, Chain Heal, Healing Wave, and Flash of Light. Test each rank with the same overheal value. Then change overheal to match different fights. Use the CSV option for spreadsheets. Use the PDF option for quick raid notes. Save your best settings before raids or dungeon reset nights weekly. Over time, these comparisons help you heal with less panic and better mana control.

FAQs

What does healing power do in Classic?

Healing power adds bonus healing to spells. The full value is not always added. Each spell receives only a coefficient-based share.

Why does the calculator use coefficients?

Coefficients estimate how much gear healing applies to a spell. They make rank comparisons more useful than base tooltip values alone.

Should I always use the highest rank?

No. Higher ranks heal more but cost more mana. Lower ranks can be better when damage is steady or overheal is high.

What is overheal?

Overheal is healing that lands after the target is already full. It reduces effective healing and can waste mana during long fights.

What is healing per mana?

Healing per mana shows effective healing divided by mana cost. A higher value usually means better efficiency for long encounters.

When should I use a custom coefficient?

Use a custom coefficient when a spell, rank, patch, server, or talent interaction does not match the automatic estimate.

Does crit chance affect expected healing?

Yes. The calculator adds average crit value by using your crit chance and crit multiplier. It does not guarantee actual combat results.

Can this replace combat logs?

No. It is a planning tool. Logs are better for real raid review because they include timing, movement, assignments, and mistakes.
