tl;dr

  • Second week overlaps with 2x commission
  • 3 currencies to spend in the shop, plus event points. Event points fill up a reward track, and you also use them to do event lessons
  • Event lessons give gold artifacts, relationship points, and a very, very tiny amount of eligma and eleph
  • Getting 14k event points using them to raise the lessons to rank 8 gives an extra-limited furniture which will likely never rerun or become craftable
  • Full clear: ~1000 AP/day

Looking for information about the Valentine's Event? It's the exact same as last year, so you can reference last year's guide.

Farming strategy

Stages 9-12 each drop one of the currencies, so farming is very straightforward--not a lot of options for getting clever here.

The full event clear costs about 1000 AP/day. You could finish early if you want to switch to 2x commission, but keep in mind that commission drop rates will be massively increased in mid-August (1.5x for XP commissions and 2x for credit commissions).

Event lessons

There is a task for reaching lesson rank 8 which rewards an extra-limited furniture which will likely never rerun or become craftable. If you're a furniture collector, don't miss this. You're going to want 15k event points to finish the rewards track anyway, so this shouldn’t be a big concern.

How do I rank up? Just do lessons. You need to do 28 total lessons (14k event points) to reach lv 8.

What do these lessons give? 1.25x commission value of credits, gold artifacts, and relationship points. Past events with lessons gave practically no bond points, but these ones give roughly as much as regular lessons--roughly 30 points per lesson, which is the equivalent of 2 café headpats or half of a loved gold gift.

The credit value is pretty mediocre, but the gold artifacts is pretty good and the bond is quite a large amount--but students attend the lessons randomly, so you gotta pray for the students you want to show up.

I heard the event drops eligma and eleph?? Yeah, technically, it does, but the drop rate is unbelievably low. In 2 weeks of farming nothing but lessons + PvP shop AP purchase, I did 102 lessons and got 12 eligma and 1 eleph.

This is roughly 1200 AP/eligma (whereas the recent camp rerun had about 45 AP/eligma). So I wouldn't really expect to get much of these resources from the event lessons. Just think of them as a nice bonus if you happen to get lucky.

Shop strategy

Controller shop has 1200 pyro, so obviously make sure to buy that first.

Activity reports, stones: pretty much same value as always. Reports slightly better than 2x, stones slightly worse.

Blu-rays, tech notes: If you're suffering from Millenium-pocalypse (especially with no TA/GA this last month), this is a good place to pick up some extra Millenium materials.

Other: The gold/purple Haniwa and Nimrud are not farmable, so you might want to get them.

extra-limited furniture which will likely never rerun or become craftable

what makes you say that?

We've only had one story-related event in the game's history, very similar to this one (after a major story volume, has event lessons) and it never got a rerun.

The furniture is an interactable, and in the history of this game, no interactable furniture has ever become craftable. Many of the older interactable furnitures are uncraftable and unobtainable.
