Feats/Gear for a skeleton compaion?

[Glarnog]

So I have a 7th lvl character. 5 levels of Gunslinger/Pistolero and 2 of trench fighter. Through rp he has acquired a 7th lvl skeleton companion. Based off a 7th lvl human warrior. I'm not sure if he'll have an int score, but the DM did say he'd have access to feats as if a PF character. So looks like 4 feats to choose right now. It is already under the constant affect of a permanent desecrate with an alter. So I was wondering about feat suggestions. Or advice. My character is a bit of a glass cannon, I was thinking of making the skelly kind of a bone shield. Currently the skelly is wielding a +1 unholy sword. I was thinking improved turn resistance might be good to have too. Also any gear advice would be cool too. I don't think he'll ever be any class but warrior.

Thanks
