What it does
Checks how many party or raid members within the distance you set of the unit specified have a health percentage that passes the comparison you set, compared with the count you set.
Why you might use it
Count the party or raid members within a distance of a unit whose health percentage passes a test. This is the natural trigger for smart group heals: Chain Heal, Prayer of Healing, Circle of Healing or Holy Nova when at least 3 nearby allies are below 80% health, and a single-target heal otherwise. Not available on Retail or Forever, where the game hides health values from addons. See also Health Percentage Within Range and Allies Within Range.
Example
The number of Party members within 40 yards of you whose health percentage is less than 80% is greater than or equal to 3
Settings
What each setting in the condition editor means, from the game's own help.
Unit - The unit this condition uses as the target of comparison.
Operator - How to compare Health Percentage with the Health value. This comparison uses basic mathematical comparison operations.
Health - The health percentage each ally within Distance of Unit is compared with, as a percentage of their total health.
Operator - How to compare Health Percentage Count Within Range with the Count value. This comparison uses basic mathematical comparison operations.
Count - The number of allies within Distance of Unit whose health percentage passes that comparison. This only counts allies you are in a party or raid with.
Distance - The distance (in yards) allies are measured against.
Same Group - Only count units in the same raid group.
Include Pets - Include pets in the count.
Uses readable positions in the same instance, or player-centered range estimates when positions are unavailable. A unit counts only when its upper range bound is within Distance. Uncertain positions, range, subgroup membership or required health/mana values keep the whole condition unavailable, including under Unless. Percentage checks require a positive maximum; empty aggregates have no result.
