Healing Efficiency Lab

Healing Efficiency Lab is an out-of-combat healing and gearing lab for level 30. It answers one question: with the gear, talents and cast order you actually have, what produces the most useful healing?

Everything is measured from your own character — your live stats and your own spell tooltips. No values are copied from another player, no numbers are invented, and anything the addon cannot measure honestly is shown as unavailable with a reason instead of a fake zero.

Type /helab to open it.

Supported healers

• Holy Priest
• Discipline Priest
• Restoration Shaman
• Restoration Druid
• Preservation Evoker
• Holy Paladin
• Mistweaver Monk

Healing Test

A deterministic five-minute test against real raid damage patterns.

• Pick a role — Tank, AoE, or a weighted General mix of both
• Pick a pressure level — a realistic profile, or a worst-case stress ceiling
• Edit your cast order slot by slot, or let the addon search for a better order
• Read healing generated, health actually restored, damage prevented, overheal and waste

Gear Advice

Ranks your stats by useful healing per point — healing that actually lands, not raw output. It also finds Haste breakpoints and tells you plainly whether reaching one beats simply gearing your best stat, so a tiny breakpoint never masquerades as a priority.

Talents

A full talent lab, not a list.

• Toggle any talent the addon can measure and immediately see the difference against your live build
• Find highest output searches for a stronger build, confirms you can actually spend the points to reach it, and marks any extra points it had to move
• Talents that score zero explain why on their tooltip — "this test does not exercise it" is never the same as "this talent is bad"
• It only ever plans. It never edits your real talent tree.

Trinkets and Mana

Solace of the Fallen, Fist of Stone, Price of Progress and Insightful Earthstorm Diamond. Mana effects are kept strictly separate from healing, so a mana trinket can never quietly distort a gear answer.

Compare and Healer Ranking

Save a snapshot, change gear, and read the difference as current minus saved — positive means your current gear wins. Healer Ranking compares your saved healers against each other.

Learn

Full documentation of what is modelled, what is assumed, and what is excluded and why, written in plain language rather than jargon. Every assumption is listed in one place per spec.

Good to know

• The addon models only your own healing, so it assumes you reach the damage first. With co-healers in a real raid, your overhealing will be higher.
• The high-pressure setting repeats the worst observed damage window for the entire test. Treat it as a comparison ceiling, not as normal raid damage.
• Results are a comparison tool, not a prediction of any specific pull.
• It is a planning lab, not a combat helper — it hides and stops calculating in combat.
