Kamidori Alchemy Meister

oh sorry I didn't read. someone posted this problem already..

reinstall the game then the three patches in full and problem should be fixed and since the save data is stored seperately you get to keep it

chest represtent various places on city map, find ones that match arena and bar and open only those.

For clean aht, you are a event in home for cleanse the mine with Sewari (before this chapter you decide if you help her or not), and after speak, you are a item to make in forge.

increase you evasion by enhancing your clothes

I've not played that route yet myself, however i can still offer some advice~

The only wind weapons available to Wil can't be obtained in your first playthrough, so use him for defense only.
Have him equip Cover 1 and Emilitas Guardian, and stand him next to her.
With that each time Emilita defends she has 2 chances to avoid all damage taken.

Emilita, im not sure what you mean when you say windweapon.
She's a mage, use her magic spells.
If you havent gained her clothing that gives her wind elemental spells yet, simply use her normal magic spell.

Her normal spells are O-magic, which stands for Omni-magic, it ignores all types of resistances, and as such should be quite effective against a golem.

Yuidora Mine / Mirage Forest somewhere.

Btw im currently at the end of chapter 3 and according to the "Yuela route" I have met all the requirements if Saerav is Uya because I havent met anybody called Saerav

Solved: the problem was the regional system. Damn, this must be the 3rd time that I find myself the solution right after posting. e_e I'll never change, it seems.
