I have asked a few questions about optimization and DPR and i dont understand how those numbers are reached.
lets take for example a monster with 15 AC and a level 1 fighter with a greatsword and +2 on strength.
i think that die average is just a simple divide by 2.
- d4 average = 2
- d6 average = 3
- d8 average = 4
- d10 average = 5
- d12 average = 6
- d20 average = 10
a greatsword does 2d6, so a average of 6 damage.
adding prof and str to the roll makes gives it a + 4 making a d20 roll between 5 and 24.
does this make a ac15 with +0 the same as an ac11 with +4?
an AC 11 gives 9 out of 20 chance to hit = 9/20 = 0.45 = 45% to hit.
then the 6 damage divided by the percentile to hit for 0.45 * 6 = 2.7 damage per round.
are my calculations correct or am i missing something?
