HOW TO SEE ENEMY HEALTH
This link is to an autosplitter plus a mod program (Hollow Knight Info.exe) that allows you to, among other things, view enemy HP. When enabled, if a player damages an enemy, their Geo counter will change to reflect the current HP of said enemy for a few seconds. This means, to know enemy health, you must do 3 things:
- Damage an enemy without killing it (this will not update your Geo-health number)
- Take note of the number in the Geo counter
- Add that number to the Damage Value of the attack you used to damage the enemy (see Damage Values for more info)
For example, say you have a basic Old Nail which, according to the Damage Values page, does 5 damage. You hit a Wandering Husk and see that the Geo counter reads 10. 10 + 5 = 15, which his how much health a Wandering Husk has.
Note that this program is not flawless and may be delayed or not show the value properly right away. Also, multi-hit moves may overlap and skew results. If you're not quite sure, either find another enemy of the same kind to hit or back out of the room/quit the game/die (for a boss) to reset their health and try again.
If, while playing through the game, you come across a value that seems different from the ones displayed on the tables, feel free to message me or add a comment stating so, and I will try to go back in and test the values myself. ONLY replace the values if you are completely certain they are incorrect.
