Calculation of decay from damage taken
When a PC receives "d" damage from a monster, the damage-volatile enmity of the PC is reduced.
Damage-volatile enmity reduction = (1800 * d)/PC's max HP
In other words, if the PC takes the same amount of damage as their maximum HP, 1800 damage-volatile enmity is decayed.
*This calculation is subject to correction by Sentinel's effect.
*From the point of view of back-line jobs, this may be too low. By increasing the 1800 value, more enmity will be decayed when damage is taken. However, this would also have the reverse effect of making it difficult to maintain enmity when receiving damage as a tank. This all needs to be taken into consideration when making adjustments.
*For healing magic, the value is half of the above calculation.
