Maybe.Knight Otu said:Judging from the character sheets, saves appear to be calculated from the better of two values: Fortitude is the better of Str or Con, Reflex is the better of Dex or Int, and Will is the better of Wis or Cha.
If so:
Tiefling wizard: +2 Will
STR 0
CON 0
For 10
DEX +2
INT +5
Ref 15
WIS -1
CHA +1
Will 11+2(class bonus)=13
Half-elf warlock: +1 Ref, +1 Will
STR 0
CON +3
Fort 13
DEX 0
INT +2
Ref 12 + 1(class bonus?) = 13
WIS -1
CHA +4
Will 14 +1(class bonus?) = 15
Dwarf fighter: +2 Fort, +2 Ref??
STR +3
CON +4
Fort 14 + 2(class bonus?) = 16
DEX +1
INT 0
Ref 11 + 2(class bonus?) = 13
WIS +2
CHA -1
Will 12
