Ok one of my player uns now a prood Level 3 Bard which just gaines Expertise feat described as followed: At 3rd level, choose two of your skill proficiencies. Your
proficiency bonus is doubled for any ability check you
make that uses either of the chosen proficiencies. Player choosed animal_handling as one of them, so to adjust auto expertise factor I first created this attribute: Expertise_prof_bonus = (@{pb} * 2) Default animal_handling_roll attribute is giving me: @{wtype}&{template:simple} {{rname=^{animal_handling-u}}} {{mod=@{animal_handling_bonus}}} {{r1=[[@{d20}+2[Proficiency]+3[wisdom]@{pbd_safe}]]}} {{always=1}} {{r2=[[@{d20}+2[Proficiency]+3[wisdom]@{pbd_safe}]]}} {{global=@{global_skill_mod}}} @{charname_output} Of course at 3rd level, proficiency bonus of 2 is good for now and with wisdom score of 16 (+3 bonus is good too). adding 'em up gives us 5 which is exactly what I see both in animal_handling_bonus attribute value and in character shoot between check box hand Animal Handling (Wis) label I tried to change static auto-computed value of animal_handling_bonus attribute to a formula something like: ( [[@{Expertise_prof_bonus}]] + [[@{wisdom_mod}]] ) However, no matter what I try, formula is never evaluated on character sheet, it simply displays as text whatever I feed in this attribute, right where there was a 5 before. Check then becomes unusable (not even able to click on it). Is there a way to force formula to be evaluated instead? Thanks
