just an offtopic reminder...
upgrading Mermaid's Coral Castle there is great need of mithril to make the Mermaid Purses that need 15 Mirthil each! I'm at 7th level and need 60 Mithril to reach 8th level.
To those who don't have the Mirthil Dragon, which is still on sale at alittle more than half price, should consider investing as this stage is difficult to complete just by 'crafting' Mirthil.
I haven't checked how many more will be needed for the other levels.. but without doubt.. much more than what is needed now to reach 10th level.
