I'm starting a new campaign soon and I plan for the first combat encounter to be a swarm of mechanical centipede drones who are scouting outside of the town for information. I've decided to make their hit point dice 6d8 + 1, but I don't know how to calculate the "average hit points" value for my homebrew sheet. I figure I could manually account for every possible roll outcome and calculate the average that way, but I know it would take way too long. Is there a faster way to determine average hit points?
The average of that would be 28. In short, the equation is; (Number of dice x (half of die size +.5)) + fixed value.
For this situation it would be; (6 x 4.5) + 1
(edit; I forget if it's round up or not for the number of dice times half die size)
Nothing ever rounds up in D&D, except PC average hit dice.

For this you don’t need to round, because 6 x 4.5 = 27. You would only need to round if there were an odd number of dice, and then it gets rounded down. For PCs you round every die up to the nearest whole number. For monsters you do the calculation strait and then round down at the end if necessary.

each die's average is half of the highest possible roll, plus 0.5.
d4 = 2.5
d6 = 3.5
d8 = 4.5
d10 = 5.5
d12 = 6.5
d20 = 10.5
The average of that would be 28. In short, the equation is; (Number of dice x (half of die size +.5)) + fixed value.

Some things do round up, but unless it’s specifically stated the default is to always round down.
