I made a little change to my character. I will give him the flaw Untrustworthy. It is the same as disturb, but the source come from the fact he is a Tiefling, and every berk know you can't trust a demon-blooded guy... ahhh, prejudice...
In excchange, I give him a bit more strenght (14 instead of 10). I find it a bit stupid to not have a strenght bonus when you are figthing in melee, this is the advantage of melee attack (when range, you don't have stats bonus to attack, but you can stay far from the action...). I give him three new feats: Takedown, Rapid Takedown and Surprise strike.
And another thing. Have you read the Factol Manifesto... you said:
Philosophy: Entropy is inevitable. The multiverse isn't meaningless...yet. It certainly isn't evolving or improving. Decay is the natural state of everything. We seek to neither postpone or hasten the natural decay of all things, and those that do are asking for trouble. Entropy will neither be compelled nor denied.
You are not exact in it, no doomguard would dare to stop the entropy, but depending on your alignement, you have different philosophy.
Lawful: You prefer to slow down entropy.
Chaotic: You prefer to fasten the entropy
Good: You prefer inaction
Evil: You prefer action
If you have it, read the alignement section of the doomguard, and you'll see.
