Fractions

[Chaostream]

Do multiclassing characters use fractional BAB and save bonuses, or do they just get what the chart says for their level.
For example
Good BAB +1/lvl
Med BAB +3/4 /lvl
Poor BAB +1/2 /lvl
Good Save +1/2 /lvl
Bad Save +1/3 /lvl

To show what I'm asking, consider a first level rogue second level sorceror
Non-fractional
BAB = 1
Fort = 0
Ref = 2
Will = 3

Fractional
BAB = 1 (3/4 + 1/2 = 1 1/4)
Fort = 1 (1/3 + 1/3 + 1/3 = 1)
Ref = 3 (2 1/2 + 1/3 + 1/3 = 3 1/6)
Will = 3

Hmmmm, good question.

Going the nonfractional route is easiest, since you just simply look it up on the chart.
Though we do have many uber players who can handle the nonfractional computations.

Let me cogitate on this one a little and I will get back to you.

[Chaostream]

No problem I only ask because going non-fractional can kill multiclassing pretty hard. I can make up a handy "how to do fractional BAB and saves chart" if it would help. For that matter, I think there may be one in Unearthed Arcana.

[ogexam]

yeah throw one together if you would... then I can post it in the rules.

I am thinking of allowing the players to use either rule... not mix and match, you non-fractional or fractional, with a warning of errors in fractional computation are grounds for being DQ'd

Below is a chart for fractional BAB calculation. Find the level, find the BAB the class gives you (Good, average, or poor, find whichever progression here matches the one in the class description), then take the fractional value from the next column. Add all fractions together (convert the 1/2 values from poor BAB progression to 2/4 values if it makes it easier for you to add to average progression BABs).

Code: Select all

Level   Good          Frac      Average       Frac   Poor       Frac
1          1          1           0             3/4    0           1/2
2          2          2           1          1  1/2    1         1     
3          3          3           2          2  1/4    1         1  1/2
4          4          4           3          3         2         2     
5          5          5           3          3  3/4    2         2  1/2
6          6          6           4          4  1/2    3         3     
7          7          7           5          5  1/4    3         3  1/2
8          8          8           6          6         4         4     
9          9          9           6          6  3/4    4         4  1/2
10         10         10          7          7  1/2    5         5     
11         11         11          8          8  1/4    5         5  1/2
12         12         12          9          9         6         6     
13         13         13          9          9  3/4    6         6  1/2
14         14         14         10         10  1/2    7         7     


This one is for saves. There are only two types of saves (Good and poor), but the math is a little trickier. To make it easy, convert to sixths, for example 1/3 = 2/6, 1/2 = 3/6, and 2/3 = 4/6, then add together.

Code: Select all

Level   Good   Frac       Poor      Frac
1          2    2  1/2    0            1/3
2          3    3         0            2/3
3          3    3  1/2    1         1     
4          4    4         1         1  1/3
5          4    4  1/2    1         1  2/3
6          5    5         2         2     
7          5    5  1/2    2         2  1/3
8          6    6         2         2  2/3
9          6    6  1/2    3         3     
10         7    7         3         3  1/3
11         7    7  1/2    3         3  2/3
12         8    8         4         4     
13         8    8  1/2    4         4  1/3
14         9    9         4         4  2/3


For example, consider someone with 4 levels of wizard, 5 levels of ranger, and 5 levels of rogue.
Wizard would give Fort +1 1/3, Ref +1 1/3, Will +4
Fighter would give Fort +4 1/2, Ref +4 1/2, Will +1 2/3
Rogue would give Fort +1 2/3, Ref +4 1/2, Will + 1 2/3
Fortitude save, converting to sixths, is 1 2/6 + 4 3/6 + 1 4/6, or 6 9/6, which reduces to 7 3/6, or 7 1/2, which you round down to 7.
Reflex save, converting to sixths, is 1 2/6 + 4 3/6 + 4 3/6 or 9 8/6, which reduces to 10 2/6, or 10 1/3, which you round down to 10.
Will save, converting to sixths, is 4 + 1 4/6 + 1 4/6 or 6 8/6, which reduces to 7 2/6, or 7 1/3, which you round down to 7.
Notice that if you just took the non-fractional bonuses your saves would be 6, 9, 6 rather than 7, 10, 7. This has a more pronounced effect the more multiclassing you do, as well.

Boy, this was a pain to make it actually display spaces and columns correctly. Hopefully now it looks right though.

Hey, I don't care about whether we use fractions or not, but could we get a firm answer on this soon? It involves a number of changes and I would like to have several days before the con to update a number of characters if we are using it.

[ogexam]

You may use either fractional or straight out of the book to determine BAB and saves.

If you use fractional you must use fractional on all, and not just part.

On your character sheet write next to the saves "determined using fractional"
