MobHealth3 Reference Guide - Vanilla World of Warcraft Addon

MobHealth3 is an addon for Vanilla World of Warcraft that estimates an enemy's health based on repeated encounters. You can use this to conserve mana by not casting a high rank spell when a lower rank could kill the mob or just to give you a better sense of how many hits it will take before an enemy dies. To display the information in the default Blizzard interface, you need the MobHealth3_BlizzardFrames addon as well. Unit frame replacements like LunaUnitFrames can natively use the MobHealth3 data.

For many more useful addons, check out my Vanilla World of Warcraft Addon Guide or World of Warcraft: Classic Addon Guide.

World of Warcraft: Classic Compatibility

MobHealth3 is not compatible with World of Warcraft: Classic. Instead, use Real Mob Health which has the same functionality.

Slash Commands

/mobhealth3 or /mh3

Command Description
/mh3 Shows the slash command help.
/mh3 precision [1 - 99] A low precision will give you a rough estimation of the enemy health right away, while a higher precision will wait until the data is more accurate before displaying anything. In either case, the estimation always gets more accurate the more you fight.
/mh3 save Toggles whether to save data across play sessions.
/mh3 stablemax If Stable Max is on, the max HP of the target will only update when you change targets. If it's off, the max HP will change during the fight as it gets more accurate.
/mh3 reset Resets the session cache and any saved data.
