This pdf is 4 pages long, 1 page editorial/SRD, ~1/2 a page content, leaving 2.5 pages of content, so let's check out this item!
The item detailed herein is an interesting blade - a short sword once wielded by an infamous panther warrior named Barassa: Composed of glossy obsidian interlaced with orange veins, the artwork is great and the mechanics are also rather interesting: The Omen Blade is a 4 short sword with a threat range of 18-20. All people and objects with the power to cast hexes and curses cast no reflection in the blade. If an action of the wielder while wielding the blade would result in a curse to be placed on him/her, the blade falls to the ground. Also, as a swift action, the blade can bestow curses on opponents - and if the wielder also elects to get hit by a curse, the target doesn't even get SR or a save. The blade can also produce an augury-effect.
The pdf also includes one page of item-cards for the blade.
Editing and formatting are good, though not perfect: I noticed some minor glitches, like the blade's ability to empathically communicate without having intelligent item stats. Layout adheres to NeoExodus' excellent, beautiful 2-column standard and the full-color artwork is awesome. The pdf has no bookmarks, but needs none at this length. The omen blade should probably get the keen descriptor or draw its keenness from its material - additional clarification there would be nice. I'm not a fan of the no-save-curse either: The curse has a fixed DC. Why not make the DC scale à la DC = 10 1/2 caster level attribute modifier X? If the wielder takes the curse him/herself, why not simply add e.g. 10 to such a DC? The item would feel much more versatile and simply more apt regarding the mechanics. The concept and curse/hex-detection abilities rock and if all mechanics would be as solid, I'd go for 4.5 or even 5 stars, but as presented, I'll have to rate this down to 3.5 stars, rounded down for the purpose of this platform.
