Creating a new deity (and favored weapon) for the pally and excluding
it as a choice for FS and Clerics have created a bit of an issue
with multi-class pally.
2 scenarios, 2 different outcomes
Level 1 take pally sacr fist ...
then
level 2 take a level of cleric ---- problem <<<<
the game will not allow you in this order of choices
to choose your deity for cleric ... it defaults to sacr fist
which does not exist in the cleric class breaking all the
clerical favored weapon stuff.
Change the order
Level 1 take cleric (choose a deity and the weapon [for this example choose
one that has a centering weapon like staff or longsword {if you take whirling steel strike})
then
level 2 take pally sacr fist.
NP - the sacr fist tree now accepts the earlier favored weapon (from cleric)
and any favored weapon abilities now work on that weapon as well.
so ...............................
The most logical choice would be to extend
sacred fist to both the cleric class and FS class ... which would
in fact create 2 more Arch classes. (prob the easiest solution
because then the new version of a pally will act like other pallies)
OR
fix the client to ask for your deity if you multiclass into
cleric or FS after pally sacred fist. (this will create 2 favored weapons)
good luck with this
If you only want a pally to have 1 deity, then you need to extend
sacr fist to clerics and FS
or block Pallies from multiclassing cleric/FS if they took sacr fist
(likely not the best choice)
