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).
Slayer (Ascendant passive)
This skill grants passive culling strike, increased damage while leeching, increased area of effect if you have killed in the past 4 seconds, and grants immunity to reflected physical damage. It also causes life leech effects to not get removed at full life (functioning identically to Slayer's Brutal Fervour node).
