Why not both?
Sum is the most important part, though.
<me> .roll 3d6
<bot> 3 + 6 + 1 = 10
I'll also need you to allow adds and display the level of the 2d6DARO rolls (level 1 is 20, level 2 is 25, level 3 is 30, level 4 is 35, etc:
Let's see if this table looks ok:
Lvl Target Lvl Target Lvl Target Lvl Target
1st 20 2nd 25 3rd 30 4th 35
5th 40 6th 45 7th 50 8th 55
9th 60 10th 65 11th 70 12th 75
13th 80 14th 85 15th 90 16th 95
17th 100 18th 105 19th 110 20th 115
The forumula for level is simple, though: floor((roll - 15) / 5)
The command should look like this:
.daro 12
It will roll 2 dice in the standard way, add 12 to it, and display the level achieved:
<me> .daro 12
<bot> rolled 2 2 + 3 4 + 12 = 23 = level 1
<me> .daro 23
<bot> rolled 1 5 + 23 = 29 = level 2
<me> .daro 17
<bot> rolled 2 2 + 4 4 + 3 3 + 12 = 30 = level 3
Finally, if 1 2 or 2 1 or 3 1 or 1 3 is rolled, it's an auto-fail:
<me> .daro 100
<bot> rolled 2 1 = autofail
<me> .daro 12
<bot> rolled 3 1 = autofail
auto-fail = botch
