The guild system seems to be well done. The combat requires more skill as you and your opponents gain abilities to use. Special resources such as Nova and Equilibrium are fairly easy to come by if you run the instances so it really is free to play, pay just ups you a little faster. Overall I think it is one of the best for this type of game.
Rogue should be either "Gain [an] extra action point." or "Gain extra action point[s]." depending on whether the gain is one or potentially more than one.
In the shop it should be either "Each weapon[] [type has a] different combo." "Some equipment [gives skills or boosts] like AP booster, regen, etc. You can also change your job class.
In the second paragraph of the next box, it should be "Try to keep all your character[]s alive because each character give[s] additional AP per turn. Once you lose one or two character[s] you will lose some AP per turn."
putting brackets around changes, the next box's text become It should be "Battle is turn base[d]. Each turn will cost AP. Your AP INFO is located on the top[.] Each character attack will cost 1 AP. You can click [a] character['s] portrait or use the Q,W,E button[s].
It should be [A strong enemy appeared] Capitalization is missing from the start of the leader's sentence, and he's talking about the trait of the boss, which is 'looks", not the present tense of the verb "look", making it -Leader: Careful boys, it looks strong...
You have an extra "I" in the word "If" making it "Iif". It should be "If you cancel a mission or die, items and gold you collected cannot be kept. You only keep your avatar lvl exp."
Though it may still not be perfect, it should be "You will find a lot of things in dungeons. It is up to you to choose to fight an enemy or to choose another path such as Dark Room, Magic Circle, etc."
When talking about more than one "hunter" it becomes the plural "hunters".
"Leveled up" is the past tense of the event "level up", but what is needed is the current/future tense of the action that causes the level-up, which is "leveling up".
"you hunter ranks." should be "your hunter ranks."
It should be "Special hunters are only available to hire after you beat them in special missions.
