A large portion of relevant modules/templates have now been switched to cargo. Various usages of SMW throughout the wiki need to be replaced by the new functions, in particular item tables. If some pages do not show up but contain no errors, please null-edit them. To see how you can help with the port check out Path_of_Exile_Wiki:To-do_list/SMW_migration (and leave a comment on the talk page if you have questions).
Lilly Roth is an NPC first met in the end of Act 5 at the Cathedral Rooftop after the character is revived by Sin following being defeated by Kitava. She then offered us a lift to Lioneye's Watch in Act 6, beginning our Part two.
