I wonder if these are the items that need to synthesize the event?
I would also like to know what is that red band writing event?<a href="ссылка;
And also like to know how do I equip this stone equipment, tried to equip the same way the other but not the right.<a href="ссылка;
Thanks in advance!

Red stripe is required for the event "Похищенные сокровища"
"Men" need for event "В поисках божественного рецепта"
Read more about synthesis here ссылка and pick up on the names
The conditions of the event ссылка
It is a stone charms. Read more on the wiki ссылка section Камнизачарования

and as the stone how can I use it?

in the Armory(Оружейная) there is a section of "Зачаровать". Insert armor and a suitable stone and all

Thank you very much !!
