Without getting into a discussion of the merits of multiclassing a cleric, I need some help wrapping my head around the actual mechanics of how multiclassing works, specifically with my concept of a Cleric/Holy Vindicator.
I plan to take 8 levels of Cleric (to get the sweet 8th level domain powers), then take 4 levels of Holy Vindicator before returning to a cleric progression.
My first question can be extrapolated to all multiclassing:
What happens with the base attack bonus if one class has iterative attacks and the other doesn't? For example, an 8th level cleric has BAB of +6/+1, and a 1st level Holy Vindicator has BAB of +1; would you:
1) Add the Holy Vindicator's BAB to all iterative attacks (my this example resulting in +7/+2), or
2) Add the Holy Vindicator's BAB to only the first iterative attack (in this example resulting in +7/+1)?
My next set of questions are specific to Cleric/Holy Vindicator:
The Holy Vindicator Channel Energy class ability states that "The vindicator's class level stacks with levels in any other class that grants the channel energy ability." When I take a level in Holy Vindicator, is it like taking a level in Cleric for the purposes of Channel Energy #d6, save DC, etc? For example, keeping with the Cleric 8/ Holy Vindicator 1 example, would this character would channel as if he were a Cleric 9? Continuing the analogy, a Cleric 8/ Holy Vindicator would channel as if he were a Cleric 12? Alternately, does the stacking of Holy Vindicator levels with Cleric levels only serve to increase the channel save DC (e.g. a Cleric 8/ Holy Vindicator 4 would channel 4d6 at will save DC 10+[8+4]/2+CHA=16+CHA)?
Assuming full-stacking of channel #d6s, etc, what happens when you return to the cleric progression from your dip in Holy Vindicator? For example, would a Cleric 9, Holy Vindicator 4 channel energy as if he were a Cleric level 13, but cast spells as if he were a Cleric level 12 (due to the loss of one caster level from Holy Vindicator)? Furthermore, how would you resolve the increase in iterative attack BAB from Cleric Level 9 (ties in with how the first question is answered)?
