Academy buff and honor points.

So I have enough points for 70lv sun weapon. But some guy said if i'll take it, i will need more graduates for academy buff. Is it true?

yes because if you buy the weapon your honorpoints got reduced (by the price of the spear)

So for buffs you need honorpoints, not graduates?

it only show you the graduates at the npc.
but the honor points are the important thing^^
if you have 100 perfect graduates (lv1-40) you got much more points than 100 graduates from lv20-40 so you will be at a much higher place with the same graduates.

When I bought a Sun level 70 bow on my account I was still on the same place in the Honor list.

I don't have the account anymore but lemme check if he's still on Gold honor buffs with the same ammount of graduates or not.

Edit.

Well I had 4.7k Honor points, sun bow is 2.5k
Right now the char is on 18th Rank with tha same amount of Graduates, so last time he gained any HP was 2~3 Months ago..

I doubt he'd even have Silver with 2.2k HP, which is only 55 Graduates.
