HP numbers

Where the number comes from

The game sends a bar's ratio rather than hitpoints, so the plugin multiplies that ratio by a bundled max HP - roughly 4,100 NPC ids - and refines it with hitsplats between updates. An NPC missing from that table shows a percentage instead.

Display Mode in NPC Bar — Style picks what you see: number, percentage, both, or no text.

Scaled encounters

Where an encounter scales monster HP by difficulty, path and party size, the plugin applies the same scaling, so the number matches the instance you are in. Minions take the same party scaling as the boss, so they keep a number in a team.

Other players

The game never sends another player's max HP, so their bars are percent-only.

Bundled data

Data	Coverage	Drives
Max HP	~4,100 NPC ids	The HP number on NPC bars
Elemental weakness	1,762 NPCs	The surge icon and weakness percentage
Known-aggressive monsters	2,831 ids	Aggressive name, bar colour and icon
Pets	445 ids	Hiding a pet's bar and name

Aggression is one answer per monster, so a monster aggressive in one location and tolerant in another is marked the same way everywhere.

If an NPC shows a percentage where you expect a number, post its name on Issues and it can be added.
