First you have to get the ingredients in the Yettie's house, basically the women well tell you the key is first, its straight forward on to get it, then she takes you the bed room, which is the boss room, you do the same with the shadow pieces, fight the boss.
What I'm trying to tell you is you have to fight the boss to get it.
no
The mirror of twilight is in the desert. you gain access through the mirror of twilight after defeating the boss of the desert temple.
in arbiters grounds, snow temple, temple of time, and city in the sky
You don't get the mirror shard from a chest. You have to defeat a boss to get a mirror shard.
warp out with midna to another area
Zant is from Shadow land. The other world behing the mirror in twilight princess
The game is about a twilight princess who goes to the light world to look for a hero to return peace to the twilight world, & Link is chosen. Link's adventure starts off with a friend being kidnapped, Ilia. When Link meets Midna the Twilight Princess, they team up. Link restores the light world back from the twilight by gathering tears of light for the light spirits. After that, they gather the mirror shards to restore the twilight mirror to go to the twilight world & return peace there.
Probably not (if you noticed midna shattered the mirror of twilight, the only thing connecting the twilight realm to hyrule, in the cutscene after the credits of twilight princess), unless Myamoto decides to do a direct sequel to twilight princess, which isn't totally out of the quuestion; see "Majora's Mask".
To find Zant you must have all 4 mirror shards. After you have them all go to the mirror chamber a portal opens and you go through it and zant is on the top floor of the twilight palace in the portal.
you find him when you tackle the 5th dungeon. you need to help the Zora kid and get his earrings. then you need to get a reekfish. then turn into a wolf and follow the reekfish scent to the yeti. you find the second mirror shard here
you get the mirror peices by finishing the dungeons (desset, time, snow, and sky). its like the thing for Midna. It appears after you kill the boss
Just use the armor u began with because all the other armor is more vunerable to attacks
