The dice formula in rollable() can use values from other fields as part of the calculation.

**Strength:** number(name=strength,value=14) (mod5e(name=strengthmod,show_symbol,value=strength,dice=1d20+n,dicelabel=Strength Check))

**Reference Field:** rollable(1d20+field[strengthmod])

Fields can reference any number() or mod5e() field within the same object or another one. Use field[fieldname] or field[objectid.fieldname].

Note: Fields in transcluded statblocks need to use the full objectid.fieldname syntax.
