So I play a barbarian with a battle ax. Last night, my human (middle-sized) barbarian was magnified by a spell of glory that made his terrible weapon even more devastating.
So we checked the rules for his new base damage. Unfortunately, the table ends at medium-sized 2d6 and becomes 3d6.
Since the medium sized battleaxes already have a 3×6 weapon damage, we tried to identify the pattern of the table that was (at least for us) unclear by 3d6, or it could be 3d10 due to the steps in weapons be with lower base damage.
So the question is:
What is the weapon damage that needs to be rolled here, and what pattern would this identify for weapons that exceed the printed books table?
