AP (Attack) Calculator
Pick your class, enter your weapon and stats. Calculates the Attack Power you'd see in the U menu. No need to look up weapon AP by hand, pick from the list. Most players just call it attack; AP and attack are the same thing, this page covers both.
Two things decide AP: your weapon's AP and your main stat. STR for Warrior and Kurian, DEX for Rogue, INT for INT Battle Priest. Mage hits with a staff so it uses STR.
If you dual-wield one-handers, the left hand's AP counts half. For Assassin both daggers count, the left still at half.
Every reverse level gives +2 stats. An 83/5 character has 10 extra stat points; the math adds that itself.
Wolf raises the result 20%. Weapon Enchant Scroll adds +5 AP to the right-hand weapon and +1 AP to the result; on Assassin it also gives +3 to the left dagger.
