Shouldn't the have a rarity of 170 (challenger loot) rather than 160 game prize? Unless there's another way of getting it, but I got it from a pylot battle.

If a challenger only shows up sometimes during a holiday or other event, is the prize a game prize instead of a challenger loot drop? I know at the time that the Large Gutting Knife was first created, it was part of the 2011 pandemic, so the loot-drop rarity didn't exist. One got the LGK then by playing the game of the site-event.

Up until now, the opportunity to challenge Pylot for this loot was not possible, and it may not be possible again for another seven-to-eight years.
