smite question

[atomicsomething]

Hello,

i have a few questions about smite and how the hit is calculated.
the formula says :
ab + CHA + d20 vs their AC

• CHA is the total charisma or just charisma's bonus ?
  
• about AB, it says temporary bonuses are not taken into account. what about STR modifier and Epic prowess/weapon focus feat ? or is it just raw BAB ?
  
• if some of the last question is not completely irrelevant, i have a last one about dexer pally/bg and weapon finesse.
  

i just want to check if there something worth trying with smite without going on full CHA boost.

thanks in advance.

can someone explain me this please ?

i think that it is charisma bonus not total charisma. also i think that temporary bobusses include prayer and bless or seplls like that. i am pretty sure that weapon finnesse counts as that is not a temporary bonus.

AB ( Paladin max BAB at 20 is 30 ) + CHA Bonus + die roll (1 - 20) vs. MOB AC

Example: 30 + 20 + 20 = 70 vs. MonsterAC: 69 = hit. (this might be an automatic hit too being a natural 20)

Example: 15 + 4 + 1 = automatic failure possibly ( going off all natural 1's are auto-fail)
