That is not true. The first one looks at index [0], while the second one is index[1].

>>if roll[0] > 15:
>>   if roll[1] >= 2:
>>       print("Success")
>>   elif roll[2] >= 2:
>>       print("Critical failure!")

This will print "Success" if the first roll is greater than 15 AND second roll is 2 or greater.

It will print "Critical failure!" if the first roll is greater than 15 AND the second roll is less than 2 AND the third roll is 2 or greater.

Hello,

I'm quite new on python, so don't hit too hard if I'm wrong ;)

A question on the logic... Does this means

if roll[0] > 15:
if roll[1] >= 2:
print("Success")
elif roll[2] >= 2:
print("Critical failure!")

that rolling multiple 1's get the priority on rolling multiple 6's? I mean result > 15 and 2 1's is always a critical success even if multiple 6 are rolled?

also

if roll[0] > 15:
.........
elif roll[0] <=15:  <--- this is redundant. already checked for > 15 so if here is always <= 15
if roll[1] >= 2:

you can change with:

elif roll[1] >= 2:

And... which is the RPG name ? :p
