Updated Euon. I took Sorcerer (Favored Soul) 6. He gets:
+1 sorcery point
extra attack (from Favored Soul sorcerous origin)
one new spell of any level he can cast (it came down to either blink or haste, and I selected haste)
3rd level spell slot
Also: I discovered an error in his hp. He should have had 37 hp at 5th level not 32 (9 hp at 1st lvl, then 7 hp each for lvls 2-5), and should have 44 hp at 6th lvl.
