This is a great little product, however, there are a few things that strike me as odd and deny this little gem being a 5 star product. For instance, the mighty ability grants an enhancement bonus to damage and attacks rolls. I can understand this choice, however, this is an extremely uncommon bonus type unless it's used in conjunction with a weapon (such as soulknife's soulblade ability), it also precludes the character from enjoying the standard bonuses granted by magic items. I would think it makes more sense for this to be a morale or competence bonus. I also noticed a slight hiccup in regards to the strength focus ability the feature doesn't describe in what capacity the unarmed strike is when using this ability (i.e. when using strength focus are the colossus's unarmed strikes considered weapons and if so how could such a character add weapon properties?). Another oddity I encountered is the fact that at 10th level the mighty ability allows the colossus to bypass damage reduction magic ... at 10th level?...See more This ability needs to be moved up to 4th ~ 6th level at the very least (which is in line with most of other classes which grant a similar ability). For a character so focused on strength I would have thought a colossus talent, which prevents/mitigates strength damage/penalty, would have been included, sadly there's no such thing. Another talent which would have made sense would be one that adds 1/2 (or whatever amount is balanced) the colossus's obliterate damage to sunder attempts. There are also a couple of grammar hiccups and whatnot but I will leave those for another day. Cheers.

Author's Addendum: I would like to share what inspired me to develop the Colossus base class. Pathfinder already provides numerous options to play a hulking strong guy that can smash enemies with their bare hands. I saw three things lacking, however. The first was simplicity of mechanics. With the colossus there is less bookkeeping and simpler math. The second thing is variety of theme. The colossus can be customized to function as nearly any kind of strong hero, with fewer restrictions on the nature of the class powers. Lastly, I wanted to portray supernatural strength in fun, new ways. Many of the colossus talents grant spell-like abilities that are Strength-based. The Mighty and Strength Focus class features grant the character the combat capability to defeat enemies with all the appropriate bonuses to get the job done. It is my hope that players enjoy this class as much as I enjoyed creating it!

You know, with a little tweaking this could make a great 'Corruption' for use with "Horror Adventures" (such as coming up with 'stains' for the Talents presented).
