Really cool weapons! Great if you want to throw something new into your campaign, reward a player for some extra effort, or just change up the way they play into combat. The new abilities add some cool stuff, some of which was definetely missing (like, giving tridents a reason to exist and not just be a martial spear). Strength based weapons are stronger too, and the bigger you are, the bigger weapon you can wield, so the STR-DEX gap isn't as great (it's still pretty big though, dex is still a god stat).
Overall, a great add on to any DM trying to bring fun and novelty to the table!
