Sephira Crystals
The eight Sephira Crystals, the source of a Spirit's power: one right-click and the Angel is yours. Names, colours, the Angels they grant and the three ways to get one.
霊結晶〈セフィラ〉 — the Sephira Crystal is the source of a Spirit's power. In Date a Slime it is an item: hold it, right-click, the gem sinks into your chest and the Angel of its sephira becomes one of your Ultimate skills. There are eight of them, one per playable Angel, and they are the only way to get an Angel.

The in-game names do not all share one format: four crystals are called "Sephira Crystal of …", the other four "Sephira Crystal**:** …". Hod (8) and Malkuth (10) have no crystal: their Angels are not in the mod.
Each sephira has its Spirit: Origami (Keter), Nia (Chokmah), Kurumi (Binah), Yoshino (Chesed), Kotori (Gevurah), Mukuro (Tiferet), Natsumi (Netzach) and Miku (Yesod). Kotori is the only one who is not a boss in the mod — see 
The Spirits.
Getting a crystal
No chest, no recipe, no trader: a crystal unlocks an Ultimate skill, so it is never found by chance. There are only three ways.
By command
/give @s dateaslime:sephira_keter
Replace keter with chokmah, binah, chesed, gevurah, tiferet, netzach or yesod. The crystals are not listed in any creative tab: the command is the only way to conjure one out of nothing.
In survival: purifying a Qlipha Crystal
Since 0.0.2 this is the only survival route. Bosses have a small chance to drop a Qlipha Crystal, the impure form of a sephira. Absorbing it as it is kills you; you have to plant it in creatures, slay them one after another, and take it back a little purer each time. At 100 %, the last host drops the real Sephira Crystal of the same sephira. All the details: 
Qlipha Crystals and Qlipha Hosts (Demon Kings).
Tearing it out of someone
The Sephira Extractor rips the crystal out of the body of a player who carries an Angel. If the ritual succeeds, the crystal comes out of their chest, rises, then falls in front of the machine where anyone can pick it up. A torn-out crystal glows, never despawns on the ground and can only be picked up after a little over two seconds.
Usage
Hold the crystal and right-click (into the air, no need to aim at a block):
- You don't have the Angel: the crystal is consumed, light flares from your chest, two sounds ring out (breaking amethyst, a beacon powering up) and your body is lifted by a small jolt. The Angel is granted for free: it costs no magicules, even to a character who has just been born and has none.
- You already have the Angel: message "That power is already yours." and the crystal stays in your hand — it is never wasted.
- The gift did not take (abnormal case): message "The crystal shatters against nothing. The power did not take."; here too, the crystal is not consumed.
Once you have the Angel, put it in a Tensura skill slot and activate it with that slot's key; switch modes by holding G (the mode wheel).
Properties
The crystal is a 3D item: an elongated almond with vertical facets, widest near the top, with a long, sharp lower point — the shape of the Keter crystal in the anime, repeated in the colour of each sephira.

The Angels
Date a Slime's eight Angels side by side: sephirah, Spirit, number of modes, costs, cooldowns, signature technique, crystal and the version they arrived in.

Zaphkiel, Emperor of Eternity
Kurumi Tokisaki's angel: a colossal clock at your back, a flintlock and a musket, twelve bullets of time paid from a time bar, the shadow and the City of Devouring Time.
