Rat killer
kill a large number of rats in the southern hidden path in the second cell. this can be done by killing the rats and then leaving the tunnel. when you go back in, the rats will have respawned.

Stomach Pain
go through the hidden path to the right and open the chest in that cell. the bread is rotten and you will take damage but it gets you the title.

Take It Back!
go into the cave south of the first bridge and sneak past the guards to get your clothes back.

Escaped Prisoner
make sure that you are wearing the prisoner clothes. go to the town to the far north from the begining and talk to the Jailbreak Village Mayor. select "we'll fight" aned then complete the quest with him in your party.

Famous Judge
get rina from the hidden cave in the south (this is required so i shouldn't have to explain) and take her to the 2nd village. talk to the wandering musician.

Craver Of Knowledge
go to the second village before saving rina. talk to the mysterious old woman and buy all of her hints. the hints will cost 100, 200, 400, and 800 gold so it will be pricy. i did this by farming the monsters to the north of the second village as soon as i started.

Expert of Pursuit
catch Francisca before she gets to her village

Steady Savings
earn enough gold to buy the Holy Sword Castle-Leg without killing the monster on the beach as suggested. you will have to be quick and farm the creatures to the north. time it to where you can kill the creatures and run back to the village without being hit by the gaint monster.

Bounty Hunter
kill the giant monsters in the northwest corner and the northeast corner with the hero castle. talk to the guard in the first village after defeating the monsters to get the title.

Firefighting Hero
step on all of the burning trees with the hero castle. this is best done by starting the mission getting into the castle. run over a bunch of enemies to build up speed and then run over all of the trees, reseting time if needed.

Mine Lover!
step on every mine on the map. i'd advise doing this with the hero castle but be my guest if you want to try it on foot.

Cannon Buster
destroy all cannons on the map except for the two that can be fired.

Ruthless Cruelty
complete the quest without saving your party members from the tower

Wind Stone
after saving your party from the tower, go to the northern-most village and talk to rurufi's master. he will give you something to collect wind with. climb the western tower 3 more times.

Famous Marksman
use the cannons to weaken the evil lord until you can no longer use them.

Cannon Hater
defeat the evil lord without using the cannons. this can be done by staying in the hero castle the entire time. use the first 30 seconds to kill all of the enemies on the map other than the evil lord. reset the time and then face the evil lord while holding the dash button (i still don't know if the castle can dash in battle)

Skivvies
complete the mission without obtaining the magma plate. (basically don't do the Snowfield Servant title objective)

Snowfield Servant
go to the eastern village which can be found by going through the cave in the middle-eastern part of the map. talk to the old woman and she will give you clothes to deliver. then go to the northwest village and talk to the old man.

Mister Faller
fall through the cracked floor way to many times. i'll leave the method up to you unless you specifically want help with how i did it.

Get All
open all of the chests in the castle. i'd give you a guide to the chests or a video but my computer is having recording issues at the moment and i don't want to right out a guide to 5 chests.

Old Man Killer
knock some sense into old people until you get it. (they don't have to be possessed for you to fight them. Get out of here, Russia suggested that you simply need to fight the same old man many times.)

Regular Customer
buy food from the vendors for 250 gold 3 times after they have been taken over. (thank you to Nitz for pointing out that this requires the food to be purchased at 250 gold and YdenMkII for pointing out you only need to purchase it 3 times.)

Challenger
challenge the evil lord 5 times before obtaining the hero sword.

Super Devil Hunter
kill all of the giants on the map.

All Members Assemble
collect all of your party members.

Last Full Course
buy food from every vendor at least once.
