Valentine's details have been announced!
http://fate-go.us/news/?category=NEWS&article=%2Fiframe%2F2018%2F0123_valentines%2FSummaryTime: January 25, 07:00 UTC to February 3, 23:59 UTC
Chocolate Exchange:
There will be quests where you get chocolate coins as enemy drops. The amount received is boosted by the Servants in your party (Class dependent, I believe the bonus is from females only plus D'eon). You can use these coins (There are coins for all class types + ALL class) to get special scenes and CEs from your Servants. The CEs unfortunately do not do anything. They're akin to the CE experience fodder (Unknown Substance *insert Greek letter here*) we got from Saber Wars. Use coins from the Servant's class to get their scene. Jeanne being an extra class uses the ALL-class coins. It's 150 coins per Servant.
There's another drop you will get to buy items from the event shop. To clear out the shop entirely you will need 36,600 chocolate pieces in total. If that's too much for you (it is for me), I'd recommend leaving the class pieces/monuments for last, unless you desperately need them (which I do).
Additionally, Nero Bride
(ugh)is a limited time Servant, with a trial quest that gives a summon ticket.
Bride's kit includes the following:
Single target Arts NP with Burn and Defense Down applied to the target afterwards
First skill: Targeted NP gen up to one ally (3 turns)
Second skill: Targeted Attack Up + Crit star gen up to one ally (3 turns)
Third skill: Targeted heal + Defense up to one ally (3 turns)\
Cards: QAABB (AKA normal Saber deck)
The gacha rateup schedule is as follows. No 4* Servants are on rateup. Nero Bride is on rateup every day.
1/25-1/26 Bride only
1/26 Artoria
1/27 Altera
1/28 Jeanne
1/29 Orion
1/30 Tamamo
1/31 Drake
2/1 Jack
2/2 Mordred
2/3 Bride only
Event craft essences:
Street Choco-Maid (5*,Increase Quick/Arts by 10% and healing recovery by 20%. Also adds 5 to coin drops of the equipped Servant's class for the event.)
Kitchen*Patissiere (4*, Increase crit star gen and NP gen by 15%, coin drops by 3.)
Valentine Dojo of Tears (3*, add Sure Hit buff, gives 3% NP gauge per turn, decreases charm resist by 10%, coin drops increase by 1.)
Melty Sweetheart (5*, event shop/drop only, increase defense against Male by 100% for 3 hits, crit star gen by 10%, all coin drops increase by 2)
We will also be getting 4 new Interludes.
1. Atalanta (NP upgrade)
2. Scathach (NP upgrade)
3. Tamamo (Skill upgrade, adds a heal to her third skill)
4. Fran (Skill upgrade, increases defense debuff on her second skill)
All of these will require the completion of London to do.
Okay, that should be everything. I might be remembering the coin drops only being boosted by females wrong. It's been 2 years.
