Rena might have found this out already (BA and BA+AF3 feet), but Wiki hasn't fixed it's page. I didn't compile this properly, but here is what it basically looked like:
Code:
Stat No BA BA BA+AF3+2
STR 100 100 95
INT 100 100 110
MAB 0 0 8
Result 539 614 678
Experiment
* Just cast without BA > with BA > with BA and AF3+2 Feet
* Check values against calculator since we know the formula for Leafstorm damage and the relevant data of the mob in question (Bees and Rabbits @ Gustaberg/Windy).
Findings
BA = fTP*1.216; You NEED the entire .216 to obtain certain values and you must keep them at the third decimal
BA + AF3+2 Feet = fTP*1.22; I tried experimenting with 1.226 and 1.216 (and adding .01 to the resultant value) and neither of those worked, so it has to be 1.22
I'm not sure how the +1 feet work, but if I had to guess, it's probably 0.218. The important thing to remember is that Wiki's "It's better than Stat+100!" rhetoric is bullshit.
Edit: Rena's 2x WSC is probably correct.
