Racial favored class bonus adding fractions from multiple places

Example: asimar sandman bard level 3. Uses asimar bard favored class bonus to increase effective bard level for steal spell.

Steal spell's DC is normally equal to 10+1/2 bard level+ cha modifier

Lets say bard's charisma is a 15, so +2 bonus. DC would be 10+1+2=13.

If I put the favored class bonus, would it be 10+1+1+2=14
Or would it be: 10+6(1/2)+2=15?

Thanks In Advance

None of the above.

It would be 10 + (3+1½)*½ +2 = 14, because Aasimar adds half level to the chosen performance, not full level.

You lost me with your math. Steal spell DC is 10+1/2 bard level+cha modifier.
I'm confused where you got the 3 and the 1 1/2,
and doing 1/2*(3+1 1/2)+ 2?

10 + 1/2 [bard level] + [charisma modifier]

The special Aasimar favored class bonus allows you to "Choose one bardic performance; treat the bard as +1/2 level higher when determining the effects of that performance."

So the DC without the favored class bonus:
10 + 1/2 * 3 + 2 = 13.5, round down to 13, basically as you said

With the favored class bonus, you add 1/2 you your [bard level] 3 times:
10 + 1/2 * (3 + 3/2) + 2 = 14.25, round down to 14

10 + 1/2 [bard level] + [charisma modifier]

The special Aasimar favored class bonus allows you to "Choose one bardic performance; treat the bard as +1/2 level higher when determining the effects of that performance."

So the DC without the favored class bonus:
10 + 1/2 * 3 + 2 = 13.5, round down to 13, basically as you said

With the favored class bonus, you add 1/2 you your [bard level] 3 times:
10 + 1/2 * (3 + 3/2) + 2 = 14.25, round down to 14

Favored Class Bonuses that are fractions never give any bonus at all unless they are whole numbers. IE: for every two times the Aasimar takes that bonus, the DC goes up by one. The first, third, fifth, etc time, the bonus does nothing.

Thank you, I now understand how and why it is calculated that way :)

It works out the same here no matter where you round down the fractions. I just said round down at the end for simplicity. But there may be other cases where the specifics of when you do the rounding might matter, so thank you for adding that, though I think you mistyped - it's the effective level that increases by 1 every two levels, not necessarily the DC (which in this case is based off of only half the effective level, +10 +cha mod.)
