An addon showing extra information for warrior-tank players in World of Warcraft:

• Displays a graphical representation of the combat "hit table", illustrating how enemy blows are likely to land: miss, dodge, parry, block, critical hit, crushing blow, regular hit
• When appropriate, shows "effective health" bars for physical and magical damage, arguably more useful metrics than regular health in many situations
• The information takes into account the player's level, skills, equipped items, any buffs or debuffs, and what enemy the player is targeting
• Both interface elements are independently movable

Note: this addon is designed to work with World of Warcraft version 1.12.1, and may not work properly with some earlier or later versions of the game.
