I've been making a mod that changes some things, among them being player health. I wanted to make all humans with endurance 5 have a health of 100, with each endurance point worth 10 HP. However, the formula always adds 90, and the player always recieves 10 health at level 1, so health cannot go below 100 on the player. I do not want to go back and change all the creature health and damage stats to rebalance it, so I ended up removing endurance's effect on hit points altogether. In order to make endurance more useful after this, I wanted to give it a boost towards damage threshold/resistance. However, I cannot seem to find a way to make DR/DT a derived statistic of endurance.

If anyone can inform me on how to change the derived statistics affected by a primary stat, or even better solve the initial issue that led to me wanting to do that, it would be very helpful.
