I was trying to build myself a Forge cleric.

They have the "Blessing of the forge" that gives you +1 on a weapon or +1 in AC.

Where do i choose if its +1 on weapon or ac?

I can only find where i tell that i have used it.

The character sheet doesn't have a function for auto-calculating that yet. What I ended up doing was adding a set of +1 armor and +1 weapons and swapping them out based on what I enchanted that day. 

Thank you very much subsistcyber.

That was as i thought, and your idea sounds like a workaround i can live with until this get fixed.

Added this to feedback to  XGtE issues/feedback - Tagging, Typos, and (T)errors! Oh Sylgar! 

A complexity is that it doesn't have to be you who gets the +1 you can apply the blessing on another party members equipment.

When I played a forge cleric we found a ring of protection, the tank wanted it for the AC and I wanted it for the saving throws so we agreed I would bless his armor each morning if I kept the ring.

Having said that the ability is similar to an artificer infusion (which can also be passed arond) which you can do on your character sheet directly (though there is a lot more to keep track of and some infusions can not be replicated by adding a magic item.

Customise chosen weapon or armour and add the bonus there.

Done.

Note: you can do this right from your sheet. This is going to be the only way to add/remove it as needed as it is too complicated to do it any other way. It remains significantly more convenient than pen and paper.

So this feature has been implemented, in effect, since you can apply/remove it as and when needed.

I see the customization bonus overrides on the weapons, but not on armor.

Odd.

Oh well, just make a magic item version copy with +1 bonus.

I would just add the customization under AC and make a note that it is on my armor, and maybe change the name of the armor to "Forge Blessed Plate" or something.
