This pdf is 3 pages long, 1 page intro/front cover, 1 page SRD/editorial, leaving 1 page for 8 new feats for barbarians, so let's check this out!
The feats are as follows:
-Battle Lust: Each round in which you crit you score with a weapon that has a x3 or x4-modifier does not count against your rounds spent in rage.
-Great Thews: Expend one round of rage for 10 minute-lasting rage power.
-Iconic Barbarian: Once per day, use a rage power normally usable only one time per rage an additional time.
-Melancholy: Suffer only half the penalty to any attacks, damage and skill-checks, but also gain only half the morale bonus.
-Mighty Stamina: Ignore the fatigued condition for 24 hours for expending 1 round of rage. The rage does not refill until you sleep for 8 hours.
-Panther-like Grace: Expend one round of rage for a bonus to dex-checks or dex-related skill-checks equal to half your class-level. Rather bland and without a bonus to reflex saves, not a good choice.
-Sudden rage: When rolling initiative, you may start raging immediately and add your Con-modifier to initiative.
-Thews: Spend a round of rage to gain access to a rage power for 1 minute.
Editing and formatting are top-notch, I didn't notice any glitches. Layout adheres to SGG's 3-column standard and the pdf has no bookmarks, but needs none at this length. The feats are great and present iconic ways to enhance your playing experience of the barbarian, hearkening back to the pulp-classics of old. For one buck, you can't go wrong here and the feats present no balance-problems. While melancholy is rather powerful and might upset some games, it can also work VERY, VERY well in a game and a barbarian in my group tested it and immensely enjoyed it - surprisingly, the feat didn't unbalance my game. With one feat feeling rather worse and boring but the rest being better, I'll practically have to settle for a final verdict of 4 stars - a great investment to add some support for the unfortunately often neglected barbarian-class.
