In an optional quest, you have to find arrow heads in Hopiris. As soon as you get off the talking boat, turn to your right. They are at the foot of the first pillar.
Defeating Xaoset
When fighting Xaoset with Sangaril, get him to take a swing at you then quickly run around behind him. If you get very close to his back in the middle of his swings then backstab, he will continuously keep swinging and you can keep backstabbing him until he dies. Make sure you are directly behind him; as he swings again he will back up and eventually you will not be able to backstab him anymore. If you are directly behind him, you keep him from backing up.
For Sangaril's quest, 'Defeat Xaoset', you must go to the Ruins of Hopiris. When you get to the door that has the intermission sequence where Sangaril explains to Maia about the Shadow Clan's rules, make sure Sangaril has any attack scroll (for example, Fire Arrow, Icicle Minor/Major, Energy Minor/Major, etc.) equipped for her ability. Enter the room. Keep using the scrolls and Xaoset should be defeated without you taking any damage.
Easy gold
In Mas Ora's district of The Munari City, go to the House of Soleil. It is the first building on your left after entering Mas Ora's district. There will be a human standing directly in front of you, asking for a loan of 1000 gold. Give him the loan and he will give you a Bodril. Keep it and later in the game he will offer to pay you back. Instead, tell him that you want to buy the Bodril for 5,000 gold. After this he will ask if you actually want to buy it. Answer "No". You will gain a little bit of experience and 1200 gold. Do not leave. Continue talking to him. He will keep asking if you want to buy his Bodril. Keep answering "No" and he will give you 1200 gold each time. Repeat these steps to get as much gold as needed. However, once you leave the area, he disappears and you cannot do it again.
Exceed the set skill limit of 10 on most skills
Get your character up to level 10 in the area that you wish to go past. For example, Sword Weapons for Maia. Then, put on the Sword Ring (+2 Sword Weapons) and your skill will be at 12. You have passed the set barrier in the game, and you can do this with just about all your skills.
Hidden items
In Miridan's Pass, you may encounter some "pirates" that shout "Run away!". Follow them and they will lead you to a cave just behind the cute creature where some nice items are located.
