How come when I level up my kensai, I only get 3 HP added? I've already set the difficulty to Normal so I would get the maximum added HP. I leveled up with 14 HP before I noticed this. any ideas?

If you are leveling up from level 9 and up (ie. 9 to 10, 10 to 11 etc.) the fighter will get three hit points everytime. He will no longer get anymore than that. Look at the tables in the back of the manual and you'll see this.

Thanks for the heads-up daeomer. Let me try to understand this:

in the manual it says at Level 10, the Ftr class has 9+3 Hit dice... does that mean from Level 9 HP it adds 3hp (as what you pointed out), or does it mean a base # of 9 + 3, thereby equalling 12?

please enlighten me some more.

Your are right on with your first call. For every level up to nine the computer rolled 'one die' for your hit points. So

Lv 1= 1 Hit die of 1-10 points
lv 2= 2 hit die so another 1-10 points is added to your original 1-10 hp
etc......
lv 9= 9 hit die so now nine different times you have been given 1-10 hp
lv 10= 9+3 your previos nine roles PLUS at level 10, 3 more points
Lv 11= 9+6 your previous nine roles PLUS your three hp you got at
level 10 and now three more points are added.

Therefore if you didn't have any constitution bonuses the most hp that your fighter could have at level 11 would be 96.

I hope this makes sense!
