Healing Efficiency Lab

An out-of-combat healing and gearing calculator. It answers one question for your current character: what actually restores the most health, and which stat should you gear next?

Everything is read live from your own character — Intellect, Spell Power, ratings, talents and each spell's tooltip. Nothing is hardcoded. If a value cannot be read, the addon tells you why instead of showing a fake number.

Supported healers
- Holy Priest
- Discipline Priest
- Restoration Shaman
- Restoration Druid
- Preservation Evoker
- Holy Paladin
- Mistweaver Monk

What it shows
- Useful healing, or damage prevented, per second for your setup
- Overheal and waste, so you can see what is not landing
- Mana at this pace — roughly how long you can keep casting before you pause
- Which stat is strongest per point right now, with the full ranking
- A recommended cast order for the role and damage profile you choose

Plan your setup
- Roles: General, Tank, or AoE Healing
- Damage profile: Low Pressure for a realistic demand, or High Pressure as a worst-case stress test to separate gear
- Healing Test: see every spell's result, edit the cast order, and test your own plan
- Talents: toggle the supported planned talents and read the effect through Compare Gear

Gear advice
- Names the single strongest stat per point for the current role and pressure, and whether it stays strongest for small, medium and large gains
- Points out a nearby Haste breakpoint only when it actually beats your best stat, so a tiny gain never reads as "get this first"

Compare gear
- Save a snapshot of your current setup, swap gear or talents, and read the exact current-minus-saved difference
- Keep up to five named comparison slots
- A verdict only appears when the two setups are genuinely comparable

Learn
- A plain-language page for every supported healer that explains exactly what is modelled, what is assumed, and what is deliberately left out — no guessing and no invented numbers

Good to know
- Open it with /helab
- It is a planning tool: it hides and stops updating while you are in combat
- It models you as the only healer, so results are an optimistic ceiling for healing and a minimum for overheal — real co-healers topping the same targets will add overheal
