this should be your path when leveling
1 - 15 = do main quest and side quest from your main city (klaipeda or orsha depending on your choice)
15 - 20 = do main quest on orsha side. no side quest until you reach lv 2 exp card since lv 1 exp card is crap unless you want adventure journal points for ranking.
20 - 30 = focus on doing 2 maps on each side after that the next quest that lets you teleport dont submit it and make it as your personal teleporter. go to the other side and do the main quest and side quest until you finish 2 maps.
30 - 50 = by the time you reach lv 50 you would still be on lv 32 map (before tenet chapel) that is if you used up all the exp card.
50 - 65 = do the dungeon (50 - 56~58 first run 58 - 61~62 2nd run 63~66 3rd run)
save exp card by this time because you are way above the map that you are questing.
65 - 70 = do all quest from 32 - 65 until you reach the map that is recommended to you. keep doing it until the map is higher than your level and use your cards until you are the same level as the map. never go beyond the recommended level unless you level up.
70 - 90 = same as above. do all main and side quest from klaipeda side and orsha side. dont forget to do the quest above klaipeda. try to use tosbase to keep track on quest.
90 - 100 = do 90 dungeon and never use exp card until you are below the recommended level from the map.
100 - 150 = do dungeon first before merc mission as merc mission is based on your party’s highest level member. do quest from both side and everything that is near your level.
keep doing mission everyday so it can cover the remaining 50m~70m exp required from 150 - 180 after you use all the exp card you accumulated
if you are not a cleric you might as well do 90 boss rush for a chance of an arde dagger since 115 dungeon is a bit crap without a good party.
