Just went to the JP wiki, the guard event section and it says: "Last Modified: 2015-07-06 17:28:59" so it's pretty much updated. But the HP table seems to follow the same rules we already know, so unless Nutaku got a notification not published in the wiki, then the current HP scaling is just wrong.

Another topic, I'm seriously considering using my free 100 Nutaku points and try the event gacha with a card revealer, to get another slayer card.
What do you guys think?
