First, let me say thanks to any responses I am able to get. I appreciate the help!
I am getting ready for a campaign on Friday (first real long term campaign so I am excited). I want to play a rogue, but the only justifiable light weapon to use is a rapier if I don't want daggers (I try not to refluff otherwise I feel like it invalidates choosing in the first place). My problem is, I imagined playing as a lightly armored swordsman, similar to a swashbuckler, but I prefer weapons that are more like longswords and can be used for both piercing and slashing attacks.
Are there any specific instances of rapiers in d&d that work more similar to a broadsword rather than just being used for lunge attacks? Rapiers throughout history have varied so much, I don't know how to imagine d&d setting rapiers to look. Thanks for any advice/input you can give me!
