About the dragon sword an rapier, they used to be permanent effect items but were too powerful*. I dont want to make them selectable because I would like to make weapons behave differently than other items. But I'm not quite satisfied with the first strike on each floor system too. I need to find something, if I have no solution I will change them to normal items.
* : At this time the mallet was also a permanent effect weapon which double damage monster with armor.
