All information related to difficulty (enemy and weapon) scaling is stored in that configuration file. Human-readable versions dumped from [[renotesfiles:game_files/1.0.0_LevelSensor.yml|1.0.0]] and [[renotesfiles:game_files/1.5.0_LevelSensor.yml|1.5.0]] are included in the repo.

[1.4.0] Flag entries for Golden enemies, Igneo Talus Titan and Monk Maz Koshia were added to the kill point table. Weapon entries for the One-Hit Obliterator and Weapon_Sword_503 were also added to the weapon scaling list. They cannot receive any modifier. (Yes, the developers forgot to add golden enemies to the config in 1.3.0.)

Interestingly, the game calculates a single point value based on the kill counter flags but calculates two separate values for weapons and enemies with two different multipliers. This format makes it possible to easily change the scaling.

```c++ float points = 0.0; for (kill_flag : this-&gt;byml[&quot;flag&quot;]) int kill_count = GameData::getIntegerFlag(kill_flag[&quot;name&quot;]); points += kill_count * kill_flag[&quot;point&quot;];
<source lang="c++">
float points = 0.0;
for (kill_flag : this->byml["flag"])
    int kill_count = GameData::getIntegerFlag(kill_flag["name"]);
    points += kill_count * kill_flag["point"];


this-&gt;points = points; this-&gt;weapon_points = points * this-&gt;byml[&quot;setting&quot;].Level2WeaponPower; this-&gt;enemy_points = points * this-&gt;byml[&quot;setting&quot;].Level2EnemyPower; ```
this->points = points;
this->weapon_points = points * this->byml["setting"].Level2WeaponPower;
this->enemy_points = points * this->byml["setting"].Level2EnemyPower;
</source>


In practice, settings have never been modified. 1.5.0 (which will likely be the last game update) still has the same Level2WeaponPower and Level2EnemyPower.

Effectively, this means that the first blight Link fights will have 800+0×400 = 800 HP, the second will have 800+1×400 = 1200 HP, the third 800+2×400 = 1600 HP and the last one 800+3×400 = 2000 HP.
