Okay, lets try that again.
The Scorpion's Damage/Attack is 1d6+4= 7.5
Attack bonus +6, so vs Armor Class 17, an 11 hits, so the hit probability is .50, for an average of 7.5 X .5 X 3attacks = 11.25 points of damage/round.
Plus Grab and Constrict. The Constrict Damage would also be 4.5 on average. Since Constrict only happens following a successful Claw Attack, this Damage will also be multiplied by 0.50: only half the Claw Attacks each round on average result in a Grab attempt. The Giant Scorpion's GMB is +12, vs. Derklord's mean CR4 CMD of 19 means it will hit on a 7, a 70% chance of hitting., so
0.50 chance of getting a roll X 7.5 average damage/hit X 0.70 chance of hitting X 2 attacks = 5.25
Add this to the original 11.25: 11.25 + 5.25 = 16.5 average DPR.
Giant Scorpion is CR 3 vs fight CR 4 which has an AC of 17 with just the attacks landing. The DRP is 18.99, which may as well be 19. The monster has about 40 hit points which is half. It's safe to say that with 3 chances he can land one grapple and constrict.
about a 48% chance that one grab attack lands. The average for that is 7.5
.48x7.5=3.6
So with one constrict you get about 23.6 points of DRP
So the actual DPR is more like 2/3 that. Again, this doesn't consider Poison, but the Giant Scorpion Poison doesn't affect its DPR. It would if it caused Con or Dex Damage, but it causes ST Damage instead.
