2-Handed Sword question.

Assuming the same str/dex, a Ribgol attacks 87/min while any normal(6) sword attacks 80/m. 87/80 = 1.0875 so the normal sword has to have 1.0875x the attack to match DPS. For 100 atk that's 108.75 or about 109 attack. Most normal(6) sword uses won't have 120 dex though so less dex lowers that 109, the attack becomes whatever gives 1.0875 of the Ribgol's range.
