So, my druid has an Animal Companion who's a large wolf with Improved Natural Attack, and Vital Strike... are there any official rules on how the different spells & feats stack? I know that two size spells won't stack, but where's the line with these things, what stacks and what doesn't:
STR = 24
INA = Improved Natural Attack (As if the creature's size had increased by one category.)
VS = Vital Strike (Roll the weapon’s damage dice for the attack twice and add the results together before adding bonuses from Strength.)
AG = Animal Growth (This alteration changes the animal's size category to the next largest.)
SJ = Strong Jaw (As if the creature were two sizes larger than it actually is.)Large Wolf: 1d8+7
Large Wolf + INA: 2d6+7 (As if Huge)
Large Wolf + INA + VS: 4d6+7 (As if Huge, Double Dice)Large Wolf + AG = 2d6+11 (Huge +8 STR)
Large Wolf + AG + INA = 2d8+11 (Huge + As if Garg. +8 STR)
Large Wolf + AG + INA + VS = 4d8+11 (Huge + As if Garg. +8 STR, Double Dice)Large Wolf + SJ = 2d8+7 (Large Wolf as if Garg.)
Large Wolf + SJ + AG = 4d6+11 (Huge Wolf as if Col. +8 STR)
Large Wolf + SJ + AG + VS = 8d6+11 (Huge Wolf as if Col. +8 STR, Double Dice)
Large Wolf + SJ + AG + INA + VS = 16d6+11 (Huge Wolf as if Col. +1, +8 STR, Double Dice)
I'd assume that at least AG + SJ + VS would stack since they work in different ways, but does SJ and INA work together they both work AS IF size was larger... or would you only get the better of the two?
Improved Natural Attack and Strong jaw don't stack. Both are treat as if bigger so don't stack.
Animal Growth increases size so will stack
Vital Strike as listed.
Just have to remember with INA strong jaw will only add one effective size category.
