No matter how I look at it, the description seems to be incorrect. For levels 1-10 the description says it attacks 2x with xx% damage and for levels 11-20 it says it attacks 4x with xx% damage. Ignoring the fact that that would mean it starts with abysmally low damage, that's not how it actually is when used. Based off of the number of hits I see and how much damage I deal, the "2x" should be "4x" and the "4x" should be "5x". Am I right about this, or am I somehow missing something?
A lot of the descriptions on skills in MapleStory is blatantly wrong. Take Sharp Eyes for an example. It says it adds +40% Damage and +15% crit chance. In reality it adds +140% damage and +15% crit chance.
For level 20 I am seeing this: And for me it attacks 3 monsters like stated. So I am not sure about what you think is wrong.
