So, 2d10 is better because the damage you are guaranteed is higher. Twice as much infact.

Ah, but your forgetting that theres a 1 in a 100 chance of rolling two 10s with two 10 sided dice. Compared to 1 in 20.
I think 1D20 would be better, heres why: When you roll a 20 sided die you have a 1 in 20 chance of rolling a 20. With a 10 sided die there is a 1 in 10 chance of rolling 10. With two 10 sided dice there are 100 different combinations (1+1, 1+2 etc). So to roll 18 there is a 2 in 100 (two possible combinations: 10+8 or 8+10) chance of rolling it. This is why i believe a single 20 sided die is better, its more likely to role a high number. Although i could be wrong, i have forgotten most of the probability stuff i learnt in maths.
