All right, you know the deal - this pdf is 4 pages long, 1 page front cover, 1 page SRD, leaving 2 pages of content for 7 new feats, so let's check them out!
The seven deadly sins are a deeply-ingrained part of Pathfinder for me - ever since the Rise of the Runelords they have been developed further and recently have seen a renaissance in Open Design's Monsters of Sin-series as well as in Rite Publishing's sin-themed templates in the last couple of issues of the FREE Pathways e-zine. Now, Owen K.C. Stephens, Super Genius Games' grandmaster of crunch, further develops the concept by introducing a new feat-subtype, the sinful feat. What are sinful feats? Essentially, they are feats, that, while not necessarily evil, draw upon the concepts of sin and thus cannot be taken by e.g. paladins. this explanation out of the way, let's check out the feats!
-Gluttonous: This is the basic for the mini-feat trees herein and enables a creature to eat more than usual and get attribute (Str, Con, Int), weapon damage or caster level bonuses as well as a bonus of 3 to saves against poison and disease at the cost of starving much faster, at double the rate, to be precise.
-Big Mouth: Grants you a 1d6 bite attack ( 1d4 for small creatures) that does not threaten areas. Boring. Seen this one done too often.
-Feast healing: Stuff yourself 15 minutes to heal as if rested Con-mod times per day.
-Gnaw: You can spend an hour gnawing on something with a hardness or DR not more than maximum bite damage x2 and reduce its hardness/DR thus. Great story-driven feat.
-Stomach Reserve: Stuff yourself with food and drink up to two potions -they remain inert in your system for up to 6 hours or until you use a swift action to activate the. Disturbing, cool, mechanically sound - I love it!
-Slurp it down: Drink two Potions in the time usually required to drink one. Ok, but again not too iconic.
-Suck it up: Ready an action to drain additional spell-slots/add to the cooldown timer of spells/spell-like abilities that hit you. Now this one is pure genius! Awesome and iconic idea, though I would have loved an 8th feat here to actually EAT the spell-effect, devouring it and gaining sustenance. Some kind of high-level capstone of gluttony...
Editing and formatting are top-notch, as I've come to expect from SGG. Layout adheres to the 3-column horizontal standard and the pdf has no bookmarks, but needs none at this length. The feats herein are rock-solid and utilize well the gluttony-theme and make me look forward to how SGG will cover the other sins. However, I also felt that a true capstone of sinful feats would have made the pdf complete - a feat that needs many or all of them and provides in turn a significant boost, like a more deadly bite, a permanent stomach-reservoir of potions , perhaps even a putrid-fart feat or aforementioned magic-eating. That being said, this pdf fell slightly short of the full 5 stars for me and thus, my final verdict will be 4.5 stars, rounded down to 4 for the purpose of this platform.
