Catching up on hit point calculations...

Hey there,

going to start a new game as a multi-classed fighter/mage soon. The question(s) this leads to is about hit point calculation.

As I understand it, the maximum HP you can get per level up are calculated like this:

Hit dice of class you are leveling up + highest* constitution modifier / number of classes, rounded down.

To give you an example, let's say we have a fighter/mage with 17 constitution, which gives us a +3 constitution modifier from being at least partially a fighter.

Hit point calculation on mage level up: [d4 + 3(fighter con modifier)] / 2 = max. 3.5, rounded down = 3 HP

Hit point calculation on fighter level up: [d10 + 3] / 2 = max. 6.5, rounded down = 6 HP

Level up on both classes simultaneously, e.g. at character creation: [d4 + d10 + 3 + 3] / 2 = max. 10 HP


Can you guys confirm this is the correct way it works? The thing I am most doubtful about is if it's really always the highest* con modifier that is used on level ups, but I'm 100% sure I recently read that in some BG FAQ.


So long,
Goodkat


*: Basically always the fighter con modifier, since all others are capped at 16/+2.
