Fighter build (extra feat at EVERY level + free exotic weapons proficiency)

I don't think you should necessarily expect to be able to craft custom items of your own invention. They're very DM-dependent. But I also don't think you really need to craft any custom items because you can do just fine with the basic stuff in the DMG.

I think there is an understanding that crafting an item that has a 5 uses of a spell per day is not really outside the realm of acceptable custom. It has a simple formula.

However, Crafting a real custom item like Gauntlets of Absolute True Strike (GoATS) that require Extend Spell feat, Spell level of 2nd, and Minimum caster level of 3rd, and “Continuous Use“ calculations allowing one attack each round to benefit from a +20 is extremely custom, and I wouldn’t expect many DM’s to allow it, even at the highly expensive cost.

Any crafting skill requires DM coordination, even for the stuff in the book, especially when the DM has already stated PHB only.
