I’m lv.164 / 11 now, and I have exp card; lv.7 x90ea, lv.8 x82ea. Is it enough to reach class 15? Do I need to grind more?
PS. It looks like hell after 2nd Demon Prison because there are no mobs on the others map. It’s impossible to grind on the other map at this point. >.<
Eating all of them will get you to level 172 or 173, and your class to 13 or 14, depending on how much % you have right now.
That is without the additional exp the card can grant. But I guess you can always do more quests.
If you are at class lvl 11 and 0%, using all your cards would get you to class lvl 13 and about 5~10%. This is without the additional exp from cards.
am on the exact same level as you are at the time of making this thread with 0 exp cards xD
You sir, will face the wall, good luck.
You can get to 175 if you grind to 167 and 20%. From there you do the 175 dungeon and other places to 186 and you will also get rank 6. So keep farming 2nd demon prison to 167, shouldnt be too hard.
am waiting for it… I think I have never “grinded” fro more than one level or 2 and I wouldn’t call it grind xD
I got lazy and spammed my 7 and 8 cards that I had at 169. I am like 173 now and I still have a bunch of places that I can get cards as well as some reasonable grinding spots.
Honestly the grinding in this game isnt that bad. I know it is x2 at this point but we will see what the base rates are at release. IMC should keep them where they are (not the x2 the base part) and have weekends be x2 or something like that.
i was 160 and i had 127 level 7 cards and you can assume i had all the level 8 cards (i think 120) and i got to where i was without too much unnecessary grind. i grinded 2 hours tops for 178-180 mainly farming for a ring recipe.
I mainly only used cards until i unlocked the next area of quests, did them until i needed more exp for the next area, used more cards, then idecided to jump somewhere from like 170-177 to get to rank 6, then i did it again and got to 180 and so on until 190. the 190 dungeon gives a ton of exp, 2 runs got me 4 levels, another 2 runs got me to 196, and the last 2 got me to 199 roughly. I still had 20 lv 9 cards remaining.
Yeah that x2 exp really kicks it when you are running dungeons.
Thanks guys, I already changed to Rank.6 class. I kept all the cards and run through quests. I used some cards to lvl up, so I could accept all the quests. No need to do any grind. 
we grind 2 lvls in 1h and am now ready to do more quests
:3 may the goddesses bless the double exp event xD
Remember you are on 2x exp, every dungeons run counted as 2, every boss at quests counted as 2, every single monster counted as 2
Without the 2x exp the grind is real and painfull xD
The only thing people need to do is stay at Demon Prison D2 for as long as humanly possible. There should be a big sign that says “DONT LEAVE HERE TILL 165”
