This event is fairly difficult for new players, with Xeno content being harder than the basic Showdown and extremely punishing to players without Fire teams.
The normal Sagittarius Showdown is also available, however, which can be used to gather most of the basic trade-in treasure for items from the Xeno event shop. Note that the inventory and material costs of the Xeno shop are separate from that of the normal Sagittarius Showdown shop
If nothing else, purchase the 20× Half-Elixirs; they provide much more AP than is needed to farm them.
Xeno Conviction Flashspear is one of the more niche Xeno weapons, as its upgraded form, the True Conviction Flashspear, is more or less made specifically with the Sage and Apsaras classes in mind, allowing them to deal significantly more damage as long as they avoid being hit. However, Wind as a late-game element tends toward all-out offense, meaning that spear classes are less common for that element. Obtaining a True Flashspear is still highly recommended if you are capable of doing so, but its use as a mainhand will depend on the characters available to you for building a team around a Sage or Apsaras protagonist.
Play Xeno Sagittarius Clash and Sagittarius Showdown at the same time!
Clash battles are harder than showdowns. When you are able to clear extreme- or maniac-difficulty showdowns you should be able to take on Xeno Sagittarius (Note that Xeno Sagittarius's resistance to elements other than Fire is notably high, meaning this statement is more of a guideline than hard truth).
Xeno Sagittarius maniac-difficulty will unlock after clearing extreme-difficulty. Nightmare battles will appear at random after beating extreme or maniac battles.
There are three levels of nightmare battles. Defeat the lower-level nightmare bosses to unlock the next one. Play to get treasure for the new event weapons!
Xeno Sagittarius now has 50% damage resistance to all elements except for Fire.
You can get Xeno weapons from this event.
Xeno weapons can either be forged into their True Xeno forms at the shop, or they can be fully uncapped on the Upgrade screen. Exclusive treasure from this event is needed to forge the xeno weapons.
A fully-uncapped xeno weapon can't be forged into its True Xeno form.
Leeching raid nets ~0.4 True Xeno Anima. 60% in red chests.
How to maximize Spear drops
Run Extreme + Nightmare 70 with Kaguya and Host+MVP raids.
Raid red chest can drop a spear. It's ~1.5% in the Host chest and ~0.5% in the MVP chest.
The increased drop rate from NM120 is cancelled out by being able to bring Kaguya to NM70. It takes about 2.8 Extreme clears to trigger one NM.
While Extreme can drop a Spear, it is very rare. However, the wiki staff does not have enough data on the Extreme drop rate to give a percentage. Estimated cost per spear is 2000 AP from raid and 2500-3000 AP from Extreme+NM70. Note that Drop Rate Boosts are very important for Extreme+NM70.
Sagittarius does a lot of damage, but does not multiattack. He gains a LOT of defense from Troposphere, and Astra Horizon deals huge damage and also neuters your charge bars, so you really just want him to not use his Charge Attack at all. Bring a fire Dark Fencer with Rain of Arrows III to gain the time necessary. Pace the first 50% well, so that you push him below 50% on the same turn that he would fill up all his charge diamonds. This means sandbagging Gravity to help waste his 50% trigger. Between Gravity and Stall, you should have 2 turns to either Break him or push him below 25% to waste that trigger as well. Finish Breaking him as necessary, then take it home.
Sagittarius, half human and half horse, is the centaur of mythology, the learned healer whose higher intelligence forms a bridge between Earth and Heaven. Also known as the Archer, Sagittarius is represented by the symbol of a bow and arrow. The symbol of the archer is based on the centaur Chiron, who mentored Achilles, a Greek hero of the Trojan War, in archery.
