Some players have already maxed out their 4 character slots and either done the quest / sold the -50 cesta already. Also, it may not be worth some players to make a new char, go through pre-searing, run to 3 different spots (1-3 hours) just for one item.
I did this quest in about 40 minutes with my warrior. And that included 3 failed attempts to solo the one stuck in a quest (rurik kept dying... eventually got a group to keep his dumb ass alive while I ran for the quest).
I think they are 2.5k TOPS. But everyone sells for 6k and claims they are worth 8k (no clue where 8k came from but EVERY seller says that's what they are worth).
