A few tips for this event

1) Chance to get slayer girls from a e-gacha is higher in 2nd half of event.
So I as a free player will wait until 2nd half before spending my 2 e-gacha.
2) Always get the N-Gacha and them to level 100 to have max bonus.
3) Dont spend Radars until 2nd half of because you get higher bonus in 2nd half.
4) Be active.
5) If you have 1000+ N-Key you will only get N-Briefcases and not any N-Keys.
6) First half of event can be finished without spending items. Doing this will save lots of itmes for 2nd half of event.
7) Having a high level help a lot because the restore items restore s lot more points.
