I'm UltraSummoner, COBRA HIGH leader.
I decided to write for all of you a little guide about ranks in game. All of you can use this guide, those who already know and who don't.
Ranks are gained by gaining rank/grade points. Rank points can be earned by:
1) Getting rank up coins and exchanging them at Karin, Ardeca for rank points (100 points each 1 coin).
2) Repeatetive quest at Crespo Abyss.
3) I think (not sure) a few general quests deal also a little bit.
Ranks list, as I know, from lowest to highest:
New Trainee > Trainee > Senior Trainee > Elite Trainee >
New Infantry > Infantry > Senior Infantry > Elite Infantry >
New Guard > Guard > Senior Guard > Elite Guard >
New Esquire > Esquire > Senior Esquire > Elite Esquire >
New Knight > Knight > Senior Knight > Elite Knight >
New White Knight > White Knight > Senior White Knight > Elite White Knight >
New Blue Knight > Blue Knight > Senior Blue Knight > Elite Blue Knight.
Such as lvls, every time you rank up, you will be asked for more rank points to rank up, than the last one.
Every time you rank up, you get 1 skill point and 3 stats points.
White Knights, as I guess, are mostly lvl 185+
Blue Knights, as I guess, are mostly 190+ (this ranks are very hard to get them)!!
My suggestion for ranking up is:
for those who got money - buy and exchange for rank points at karin, Ardeca.
for those who aren't rich enough for it - quests at Crespo Abyss. quests there are easy, and you get there 3,000 rank/grade points each quest you fill. In addition, you can also get there letters coins of "DEKARON SUMMER FESTIVAL". when you get a full series of this, exchange the WHOLE sentence at once at Karin, Ardeca (DON'T exchange the words one by one), and you get 100 rank up coins per each full sentence.
I wish you happy ranking and lvling, and feel free for questions and comments.
best regards, Dvir, UltraSummoner.
