Krowaz / Bifrost / Unseal / Dragon Armor ! NEED HELP !

[Demonhao]

Hi,
I played at old usko 10 years ago, but I stoped and lost some important things.
I've played this new version since October and there is something that I don't know yet.
I have 3 questions :
First Question : I bought a krowaz part and I'm wearing it, I'd like to know how to unseal it. Anyone can teach me, pls ?
Second Question : I've asked for many ppl on server ( Anatolia ) already and nobody can explain me why I can't enter on krowaz/bifrost. Anyone can explain me, pls ?
Third Question : I'd like to know how I can make Dragon Armors ( Like Trial's, Dragon Scale, Mythril... ). Anyone know it ?


Thank you.
