I know how you can make a suspicious box to appear... Meow...
You can even find a [%dic:STR_DIC_key_world_event_Koschei_Niddle] from the summoned box.
Could Daeva help me, meow?
Not every box has a [%dic:STR_DIC_key_world_event_Koschei_Niddle] in it, but I trust Daeva to find it, meow...
I'll leave it all to you, Daeva. Meow...
Talk with [%dic:STR_DIC_N_event_Matroskin].
[%dic:STR_DIC_N_event_Matroskin] knows of a way to weaken the power of [%dic:STR_DIC_N_event_koschei]. Go and hear about it.
You received a coupon from [%dic:STR_DIC_N_event_Matroskin], which can summon a box that holds a [%dic:STR_DIC_key_world_event_Koschei_Niddle] that can weaken the power of [%dic:STR_DIC_N_event_koschei].
