hpconbon.2da

This file defines constitution influence on the creature.
First column is the value of NPCs constitution.
2nd column is the HP bonus for all classes except warriors.
3rd column the same as above, but for warriors.
4th column refers to the minimum possible roll for Hit Points before the bonus is applied. Normal and Easy difficulties ignore this Min_Roll column as they grant the maximum possible roll for the class involved, plus any bonus.
In other words, if I'm a human fighter with an 18 CON, I can roll any value from 1 (Min_Roll) to 10 and then add my bonus. With Easy and Normal difficulties, the fighter would always roll a 10 + bonus, ignoring the Min_Roll value.
5th fatigue bonus for constitution.
6th column as the name states, the rate of regeneration modifier for the Nameless One.
7th column defines the Hit Points granted for the first level.
