The task “Battle for Gungnir” is a bit outdated, I think. Lots of players have the parts, while other players don’t have enough parts for Scylla.
So, based on the mono/xeno task, where you can choose what you like/need (10 monos or 10 xenos), how about changing this task, and allowing players to chose the parts they need?
Anyway, the routers needed for Scylla seem to drop very rarely, in Trade there are very few and they start to cost a lot, around 2-3000 each!
