multiclass HP

[Thrain]

i've always wondered why multiclasses suffer so much when compared to dual classes in terms of HP. now, i understand that a pure fighter dualed to whatever will get more HP but it seems to me that a F/M/C gets so little HP compared to the rest. can anyone explain how it's worked out (i'm looking at coot or UU)

From what I've observed I'd say multiclasses get half the HP at each of their level ups.
Example:
A fighter/mage with 16 con
gets (1d10+2) / 2 = 1d6 HP each fighter level
and (1d4+2) / 2 = 1d3 HP each mage level
Once the HP progression becomes linear (+3 for fighter, +1 for mage), those numbers are also halved. Unfortunately the game seems to always round down, so the +3/+1 effectively become +1/+0.

While I haven't verified it in the game, this is what I recall from the actual D&D rules.

For multi-class, you determine your hit points as normal, but then divide by the number of classes.

So for example:

F/T - level up as a fighter, you get 1d10 (+Con bonus). Say you get 8, and you have a Con bunus of 4. That would normally mean 12HP. But because you're 2 classes, you get half that, or 6HP.

Now that F/M/T. Again, you roll 8, add Con to get 12. But now because you're 3 classes, you only get a third, or 4HP.

The difficulty setting also influences the whole HP thing. On easy setting, you'll get the maximum possible bonuses.

On easy you'll get always the best die roll (i.e. 1d10 alwasy results in 10), but that doesn't matter anyway once you reach level 10 or so from where on HP progression is fixed (difficulty setting doesn't change the fixed values).
