The second installment in the series is 5 pages long, 1 page front cover/introduction, 1 page SRD, leaving us with 3 pages of content, so let's check this out!
After an introduction to the concept of legendary items, we get the Helm(s) of the Hydra - created once by the dreaded cabal known as metabolic masters, these helms enhance the collective powers and get additional powers when linked to bigger collectives as well as the ability to meld with others into an effect duplicating the form of doom-power. The item has 5 power levels and the pdf also includes the rules for having a collective.
Editing and formatting are top-notch, I didn't notice any glitches. Layout adheres to a 2-column standard with no frills and the pdf has no bookmarks, but a cool piece of original b/w-artwork. This item is mechanically much more interesting and cooler than the first item and the narrative is also more complex and has the superior hooks implemented in the background. However, the Hydra Helmet only has 5 levels of power progression compared to the disruptor's 10 levels, making the item slightly less versatile. This remains my only gripe, though, and thus I'll settle for a final verdict of 4 stars for this rather good installment of the series.
[4 of 5 Stars!]
