Ys: The Ark of Napishtim Hints for PSP
They aren't unbeatable. Trust me. There are some strategies to defeating the bosses, you can find them if you look at a Walkthrough for this game. The best thing to do is make sure you have your swords leveled up as much as you can, and have yourself leveled up as well. -Kat
Highly Upgraded Swords: To upgrade your swords by alot, beat the wind trial in the first village. You will get a choice between gold, emel, and level. Choose emel and you will get 1000 emel. Now you can upgrade your swords as many times as you want (as long as you don't run out of emel.)
Lots of emel: Go the port rimorge and leave out the other side. There is a field where almost every kill gives you emel. And beyond there, theres a mountain where almost all the monsters give you 5 emel.
