All Spell Save DCs are way too high for me.

As you can see I'm a (relatively low level) warlock. My Save DC should be 8 + 4(Cha) + 2 (Prof) = 14. It's possible I've screwed up something somewhere, as it's all the Save DC's which are crooked. Does anyone have any ideas?

Ugh, never mind. There was a "Spellcasting Save DC" in Core Stats, which I've dutifully filled in to be 13 (8 + 3Cha + 2Prof) - and it actually added this save DC to the calculation.

The section on the core stats page is for bonuses to various fields. For example, suppose you got a magic item that gave you a +1 to your spell save DC....you would enter 1 in the relevant field and it is applied to across the sheet Or an old war wound had left your sight damaged making it harder to make ranged weapon attacks, you could add the reduction here and it applies across the sheet

Yes, I realise that now, I was just confused as it was the first time I filled in the character sheet this way, it also explained some weird values on attack (same problem, different field :)) In any case, all's well now, but thanks for the clarification :)
