And I too ask for brobat's motion to be included. He'd just not "visit", much like watcher does, in terms of mechanics. Hell, Ninja would be immune to Losers role/379.
@Brobat I agree with this! Lucid, can you please extend ninja's abilities to outside of trackers and watchers while you're at it? As well as the free kill during the day with lightkeeper dead. This would make the role so much more usable and interesting!
This role should not simply be immune to detection from trackers/watchers but should outright not show up or be 'caught' by any role which checks/responds to visits. For example, a Ninja should be able to visit Granny but not die since she didnt see him visit her. I hope people understand what I am trying to suggest.
