Zitat von der Beschreibung des ersten Patches
A health Bar for NPCs and creatures has been added for when you are in combat. An orange health bar for the creature or NPC you are currently in combat with will now appear above your own health bar on the lower left part of the screen. This health bar will only appear when you are attacking a creature or NPC and will slowly fade out if you stop attacking. It will also update to a different creature or NPC's health if you switch targets in the middle of combat.
