WHY Impact lv 7 instead of 10? and why mp boost 9 instead of 10?

As title, what give impact 10 instead of 7. And what mp boost 9 instead of 10?

 

Impact at level 7 is already instacast. most people get impact for combo purposes and not for actually as a damage skill. Not sure bout mp boost.

 

Mp boost depends on ur mp i guess, if it ends with ~70, would get lv9. Mp boost 1 lv = 30mp

 

Oh thank you guys. But impact 10 have more tumble success?

 

Some people don't use it for the tumble but for it's efficiency within a combo and how it cuts the mp of the next skill in half.

 

Impact lv10 for higher tumble chances. Idk the mp one. I actually don't use it..

 

if i remember correctly MP Boost gives a full mana bar every 3 points into the skill so in turn you would only need 9 points into it like having an extra skill point laying around

 

Non-staff weapon
Impact lvl 7 tumble chance = 50%
Impact level 10 tumble chance = 65%
Staff weapon gives +25% success chance

Not really good as interrupt and 3 sp for just an additional 15% seems like a waste(If you're not using staff). If you have lots of spare sp and want an interrupt but don't have a better one then I guess you could level it to 10.

 

Thank you boys.

 

I prefer lvl10 on my 2h and tank. 15% is a lot more noticeable and useful when soloing/tanking. Especially useful for tanking multiple mini boss like odelon.

 

it's 30mp per skill level, 300 at lv10
lv9 has only 270mp

 

Ah figured I was off a bit with my math
