Well, I've actually already built him, he is for PFS. I have a pretty good focus on where I want to go with him, but mainly looking for suggestions on how to raise my CMB, whether through magic items or otherwise.
Shamus Xavier Zhorg
A little backstory on him. He has the Giantslayer trait from the Giant Hunters Handbook (yes, I have the boon), so he is a larger than normal human. 6' 10", 365 lbs, flaming red hair and extremely large hands and wields a Large-sized Greatsword.
For how big he is, and how effective a fighter he will be, his first love, and eventual goal, is still retiring from the now necessary adventuring life and open up his own store. He is of course Exchange faction, and even took Skill Focus: Merchant, as one of my 1st level feats. Here is what my feats look like so far:
1st Skill Focus: Merchant
Weapon Focus: Greatsword
2nd Combat Reflexes
3rd Power Attack
4th Furious Focus
5th Improved Overrun
6th Vital Strike
7th Charge Through
8th Improved Critical: Greatsword
9th Greater Overrun
10th Greater Weapon Focus: Greatsword
11th Improved Vital Strike
What I envision my character in combat is very much like Juggernaut in X-Men. Due to the minuses I am taking with wielding a Large-sized greatsword and through my archetype, he is mainly going to be a first attack offense. Charge (overrun) and attack, attack once and move, and so on. There may be times I stay in one place for more iterative attacks, depending on the situation, but it will be the exception not the norm.
Yes, I know there are better overrun builds, especially in using a Barbarian, but this isn't focused solely on overrun as indicated in my other feats.
What my main question is what methods are there for me being able to raise my CMB, looking mainly through magic items? Right now I am looking at around +21 at 9th level (depending on which items I have), and I know that just isn't going to be enough, especially considering I need to beat their CMD by 5 to knock them prone. I am relatively set on my feats, unless I hear something that would be clearly better. But I do want to stay with the Vital Strike route, as well. Also, would you recommend a better order for the feats that I have? I had Weapon Specialization in there for the longest time, but just couldn't find the space to keep it in. I projected I will be doing in the area of close to +20 (at 9th level and with Power Attack), so I figured losing the +2 would be an acceptable loss.
Thanks for those taking the time to read and any suggestions would be much appreciated. :)
