I read in the General messageboard a question regarding the Enlargement personal spell. In the Flood festival chapter, Tongeater have an Enlargement person potion. I know that when he have it his equipment enlarges with him too. Does it mean that his sword increases also one step, thus doing more damage as per DMG? I think the answer is yes, but I post the question here, just to be sure. Thanks.
Yes, you're right.
Absolutely right. A large falchion would do 2d6 damage, if I'm not terribly mistaken.
