As above. 10+Level + proficiency rank + casting mod. (Technically it's "10+Proficiency+Casting Mod" but "Proficiency" is just your level plus the bonus from your UTEML rank.
And for any other kind of DC (Will DC, Athletics DC,etc.) it's just your bonus to that skill/save plus 10.
The updated character sheet from errata actually breaks it down into its components for you, I believe.
