6 Nonmagic Weapon Qualities for Weapons follows the standard look and feel of the Bullet Point series, so let us not waste time discussing those points, and get to why you are here, are these qualities worth it...lets see.
Weapon Qualities are a great thing to add to a weapon to help set it apart from the standard, without having to invest in magical enchantment, so I'm all for a larger variety, as options are almost always a good thing. First up we have the Back Spike, the classic spike of the reverse head of a hafted weapon, allowing for not only normal damage, but piercing as well. Basket Hilt trades off the option of 2-handedness for a better advantage against disarm/sunder attempts, as well as a shield bonus during the full defense action. Flamberge refers to those blades with an undulating pattern to them, causing some issues for a foe during parries. Although this weapon quality is written to allow pretty much any fantasy weapon to take it, I cant help but think this one I might limit to just the blades at my table. Ringed adds metal rings to a bludgeoning or slashing weapon, increasing damage from weight at the cost of some accuracy in attack. Ending with Springy is that quality for the player who understand the advantage of having a normally rigid melee weapon be on the more flexible side. Gaining a bonus vs. sunder/disarm against the player, this quality comes with a negative for when you attempt sunder moves of your own.
Parry Hooks are mounted spikes aimed forward upon a weapon designed to intercept and complicate parry maneuvers in which a foe will “ride” your weapon down to your hands. Now, given my initial read, I couldn't help but notice this quality blatantly states that it is the same thing as the Flamberge quality...but wait, wha? Hang on, have no fear folks. There are subtly differences here. First off, flamberge states that in a fantasy setting it "can" be applied to weapons other than blades ( of which I have already given my opinion), where-as the parry hooks make sense for hafted weapons such as spears, pikes, heck even long axes. Secondly, and this truly to me was the most important factor in deciding these two qualities are in fact different, the fluff. I personally would never build a character carrying a wavy bladed sword...sorry, I think they look stupid...my personal opinion. But, they idea of a well placed parry hook along the length of a two-handed sword...that I can get behind. In the end, the parry hook is far more restrictive in what types of blades are allowed (it lists the bastard and two-handed) then the flamberge, which further separates these two qualities.
Are they almost to similar to be in the same product as two separate qualities? Almost. But if Owen had included parry hooks later, I could see folks accusing him of simply re-skinning the flamberge anyway. Should he perhaps have written a "bonus" feat to make sure folks didn't feel cheated? Maybe...but he didn't. Is this collection still worth it? Of course.
After going back and forth on this one. One the one hand two of the qualities were nearly identical, which essentially would mean we got 5 for the price of 6 and the PDF failed to live up to it's promised material. On the other hand, they are not the same, they share some similarities in crunch, but that is all. One specifically permits non-bladed weapons, the other assumes in a fantasy setting it might be possible. Not to mention the concept of fluff, which to me is just as important as crunch...always has been, always will be. Without fluff, we are playing a boring board game of math...pure and simple. Taking this into account, I feel this PDF did deliver on the promised 6 qualities, and rate it at it's deserved 5 star rating.
