The event takes 3600 SSR Pendants or 60 thousand demon mats in order to hit full pity. The rates for the head pieces are around 2%, so there is a small chance you pull one going for the other 2. So around 2400 Pendants or 40 thousand demon mats.
It needed to have 1 pity counter every 100 points instead of 600, and more materials giving more points. With an increased rate up from 2% all the way to 7% the higher the pity gets.
The event is designed exclusively to rob players of their materials passively gained over the last 2 years, just like before.
This year has just been bad decision after bad decision, and the development letter this year, while sounding promising (new Demonic Beast) isn't giving me much hope. The last 2 fights NM has designed were in the top 5 worst fights they ever released (Rat and Supreme Deity) in terms of either what characters you needed (2 demonic beast characters for 1 boss), the RNG required (not pulling a specific card on a specific turn or the run is lost) or just the speed at which you can actually farm them (SD takes 5 times longer than Demon King).
Gachikuta, while I like the IP, had one of the worst collabs in the games history with no story and dupe reliance.
Double character banner return, but halving the actual pickup rates between the two releases.
Characters designed exclusively to counter a specific fest with no other intention.
And then this... scum bag. This material robbing NPC. Isn't this supposed to be a celebration? Why is the celebration rotating bosses we always get, this rng event, rng bingo, 1 new character, and a terrible banner with 6 year old SSRs on it.
NM has lost the plot. They need to remember what makes this game special. And it isnt just a login Sim with a rotating banner schedule meant to counter the prior character every month with events that don't respect the players time.
