Hardcore Dream's End is not hardcore enough

Due to how slowly Aeon HP scales compared to damage dealt, the player is able to OHKO all aeons at max stats, and this is not substantially better at lower stats.
It is therefore desired to increase the hp of possessed aeons, for which I've devised a formula using some control points and best fit algorithms:

float hp = (float)aeon_hp;
if (hp > 57500) {
    hp = 0.000338247901638203 * hp*hp - 2.83174710355602 * hp + 3721.80333219416;
} else {
    hp = 98881.2957 + 78390.3651 * Math.Log(hp);
}
aeon_hp = (int)hp;
