To calculate your attack, use the following formula (courtesy of Phobos on KnightsUnited.com):
Non-master attack = (0.00044293 * level * AP * DEX) + 3
Master attack = (0.00047122 * level * AP * DEX) + 3
Those formulas are not exact but they're very close. With Strength of Wolf, your attack goes up by 20%.
Hopefully this helps eliminate topics asking how to figure peoples ap out with certain items etc.
