Note on the formula, since it can be confusing and is also a bit mistyped :/
Huge thanks to TheFranchise for bringing this back up and helping me figure it out more accurately
Quote (Previous Formula)
(Shield Base + Holy Shield bonus + Grief bonus) * (1 + Smite %ED bonus + STR %ED bonus + Fanaticism %ED bonus + off-weapon %ED bonus) = Total damage
It SHOULD be read like this:
Quote (Correct Formula)
(Shield base + Holy shield bonus + Grief bonus) + (1 + smite skill ED + Strength bonus ED + Fanatacism ED + offweapon ED bonus)% = total damage
Obviously the last bracket's final number is added up as a percent.
Example (hypothetical numbers): first bracket adds up to 500 and second bracket adds up to 1200.
500 + 1200% = 6,500 = raw smite damage
Afterwards be sure to apply pvp penalty and % damage reduction etc etc to guage how much damage you're doing to a certain opponent.
I really, really, REALLY suck at math, thus it wouldn't surprise if I still made an error or didn't to the best job explaining this. Apologies in advance
