I have no Lacreous currency, this option is available but the description is: Your own skill in this area is considerable.

Also the ID of the branch is different. For me it's 262849 Success text is also different (<a class="external free" href="https://www.fallenlondon.com/profile/Silent_man/34373062">https://www.fallenlondon.com/profile/Silent_man/34373062</a>)

Might be a different branch but no unlock condition is shown even with FL quality lantern.
