亡国の四騎士 Quick Event Guide

New event is a story event, works as follows. You can access the event page by either clicking on the banner for it on My Page, or clicking the tiny thing above "Extra" and "Multibattle" on the stage select. Either way, the thing you want to click on says 亡国の四騎士.

Story events, you do a bunch of runs of story for 0 AP. You'll get crystals and experience doing these, and it's free. Do these for enough chapters and eventually you'll unlock a Raid battle. You'll need to get past that to unlock the next chapters, and eventually one more raid battle. You will also have unlocked a handful of solo quests that cost 10 and 15 AP. All of these will be accessible from the event page's front page.

There's thus two kinds of raids you'll end up unlocking access to host. One is 2*, the other is 3*. To host, they're 20 and 30 AP respectively, but more importantly, they require summoning materials. You get the materials to summon the 3* raid from the 2* raid. The materials to summon the 2* raid are, meanwhile, dropped from the extra 10 and 15 AP solo quests. However, you don't need these materials to join in with BP - so the typical optimization route is "Use BP to join 2*, get materials to host 3*".

In addition to general drop luck, you get 3 kinds of things from doing story raids. You get Medals (Bronze/Silver/Gold), Points, and Tickets. You get Medals from wooden chests in the raids (Bronze are in the solo quests and are mostly not worth the effort). You get Points based on the contrib you provide during a raid (with a bonus to points for hosting). You get Tickets based on the difficulty of the raid, plus a bonus for hosting and for MVPing.

You can claim rewards from these from the middle tab on the event page. On that tab, the leftmost button is the Box Gacha - this is a fixed size gacha that you roll using the Tickets. It contains typically an SSR summon for the event as the top prize, plus some SR weapons, and several other generic prizes. Of note, there's a lot of Points to obtain from rolling gacha, if you're not strong enough to make a lot of contrib in battles yet. There's 4 boxes you can open, you can reset the box after rolling so that for example once you've gotten one summon you can move onto the next box. Each subsequent box has more excess in it, however.

The middle and rightmost buttons are the medal and points prize claims. Unlike tickets you don't spend these, you just accumulate them and claim prizes from the pages as you hit various thresholds. Most of the prizes are AP/BP refills, more tickets to roll with, as well as more copies of the SR weapons. Of note, there's an SSR weapon that's also present in there, typically 4 copies that you get at 300 gold Medals and 1m, 2m, and 3m Points.

Some time during the chapter progression, you'll get Lancelot in your party temporarily. He gains "bond points" for being in your party for battles. When he accumulates enough bond points, then you will gain him permanently and gain access to his Fate Episodes. Normally, you get the character at the start of the event, rather than midway, but well this event is weird like that.

Even if you don't have much interest in Fire at the moment or down the road, it's still useful to try out the event. Everything it can drop will be a good stat upgrade over the Rs you most likely have as your main armaments.
