Get the four parts of Cafrisun set (just type āCafrisunā in market and look for glove, boots, armor bottom and upper), then get buffed with sacrament and blessing from a pardoner in town. Youāll level super easy to 50.
When you get 50, buy one exp tome and pop it right before you do all three runs in the lvl 50 dungeon. With you as a priest your group should be able to do it in less than 20 minutes (so you need only 1 tome for the 3 runs). Try to level up your blessing attribute as much as you can afford before the dungeon runs.
After the three runs, I usually end up at level 66 (with the tome). Then i head to gate route and do just the main quest there so I get the revelation for +3 additional status points. After that, I tend to skip all maps up to akmenās ridge because thatās when you start getting lvl 4 exp cards. Do the quests in royal masoleum and if you are 9 levels below the map then head to orsha (there is a shortcut from gateway of great king to pelke shrine ruins) and start doing the quests there. Finish the royal masoleum quest for more 3 status points and jump to belai forest to get yet another 3 points from the main quest there.
After that you should end up around lvl 90. I stop using my cards at level 90 and save them in case my daily dungeons are ran out (I usually go from lvl 1~90 in one day). You can either save your cards and do the dungeon the next day (then pop the cards after the runs) or just pop them anyways and screw the dungeon runs. Remember the maps: Stelle road, goddess ancient garden and escanciu village all award 1 status point each.
Then just keep doing quests up to level 140 where you hit āthe wallā. There will be a lot less quests to do and you might need to focus on your daily dungeons to get the remaining exp. Save your exp cards and do the 145 dungeon as many times as you can because the 160 dungeon sucks. Remember to do the daily quests in fedimian mercenary outpost and explore all maps to 100%. If you completely run out of things to do then start hunting the mobs achievement to get 1 exp card per type of mob.
Look up an exp table online and do the math on how much exp you currently have and how much youāll end up with if you use all your exp cards (to calculate what level youāll end up with). If you do it correctly saving enough exp cards, you can jump from 145 ish to 175.
There are some spots you can grind in (like bee farm) but I strongly suggest against them. Itās really slow grinding and I only do the very minimum to get the exp card achievement for mob hunting.
From then on the game will be mostly doing the quests when you can, fedimian daily quests and dungeons when theyāre available. Some grind maps are actually really worth it grinding (like alemeth forest).
Sorry I got kind of carried away and wrote a leveling guide instead of a chaplain build advice.
