Missile damage limit: A missile weapon cannot do more bonus damage than it's maximum damage it can do by itself.

An Arrow (1d6) +3/+4 fired from a Bow +5/+2 does 1d6+6 damage by itself, so it's overall max damage is 1d6+6+12 = 1d6+18.


Natural 1: A natural 1 on a to hit roll indicates an automatic miss. There are no "fumbles".

Natural 20: A natural 20 on a to hit roll indicates an automatic hit. There are no "critical hits".

Optional Rule #1: A natural 20 does double damage if a (nonautomatic) 20 would have hit the target.

Optional Rule #2: A natural 20 allows another bonus attack this segment versus that same target.


blahR (MR, PR, RR, etc.):

See [C9] for the effects of blahR. blahR's are lowered by 5% per caster level above 12.

If you have multiple sources of the same blahR, use the following calculation:

Net Resistance = (highest source) + (2nd highest)/2 + (3rd highest)/3 + ...

Thus, if you have 60% MR, 40% MR, 30% MR, and 20% MR, your total MR would be 60 + 40/2 + 30/3 + 20/4 = 95%.
