School of Crystal Magic (New arcane tradition for wizards)
The school of crystal magic deals with the creation and use of specialized crystals to both store information and to focus, store, and control magic in ways foreign to more traditional arcane practices. Precision, order, and control are emphasized. Therefore, crystal mages tend toward more lawful alignments. Chaoticly aligned crystal mages are rare if not unheard of.
A crystal mage’s powers depend on having crystals they have prepared to focus and receive information and magic so such a wizard typically has multiple such crystals on their person. They favor crystals and crystal orbs as an arcane focus because crystals they have modified themselves are needed for many archetype features. If they aren’t using a crystal focus or a crystal orb focus, their wands and staves typically have at least one crystal mounted on them. Such foci will all fulfill the requirements for any ability below which says it requires a crystal.
Crystal Lore Savant
Beginning when you select this school at 2nd level, you can alter a crystal’s structure to store information. Images and written words can be stored in a crystal for later retrieval at a cost similar to creating a book. A crystal that has been prepared into an arcane focus may also be used as a spellbook for the same cost as a blank spellbook, recording your spells and then using the crystal to prepare your spells. The deciphering, recording, and making extra copies of spells uses materials and time of the same cost as those for a standard spellbook.
These information-storing crystals do not radiate magic, but someone may discover their nature upon careful investigation with a successful intelligence (arcana) check—DC 15, at which point they can slowly begin to decipher and translate the information within, a tedious and time-consuming process. Another crystal wizard will recognize it automatically and be able to retrieve the information as easily as reading any book. The spells in a spellbook crystal from another wizard can be deciphered and copied at the same cost as from a standard spellbook. However, a wizard who is not a crystal mage needs quadruple the normal time to do so (8 hours per spell level).
Starting at 2nd level, you can cast some spells using a crystal spellbook without having prepared them ahead of time. You can cast half your level worth of spell slots, rounded up, without having prepared them, as long as you hold a crystal spellbook that stores those spells. You must expend the slots as normal to power these spells. These levels can be cast in any combination. For instance, a 5th level crystal wizard can cast 3 levels worth of spells in this manner. He could cast one 3rd level spell, three 1st level spells, or a 1st and a 2nd level spell without having prepared them. Once you complete a long rest, this ability is restored.
Crystal Spell Vessel
Starting at 6th level, you can cast a single spell into a crystal focus, storing it there. You may not use this ability again until you finish a short or long rest. The holder of the crystal can then activate the spell with a command word that you choose using a bonus action. Any material components are required upon the initial casting but not upon activating the crystal to discharge. The spell attack bonus or spell DC is determined using the crystal wielder’s intelligence. They may also add their proficiency bonus if they’re an arcane caster. The energy of the spell fades from the crystal if 24 hours pass without it being cast, if you use this ability again (with any crystal), or if you use that same crystal for Aggressive Spell Vessel (see below).
Starting at 10th level, you can alter the structure of a crystal focus such that you can then channel your spells through that focus to enhance them. When you use this ability, choose one of the following effects for any spells cast with this focus in hand:
- Increase the attack bonus by 2.
- Subtract 2 from one enemy’s initial saving throw versus any spell.
- Add 2 to ability checks you make when required by your spells (e.g. Dispel Magic, Counterspell, Telekinesis).
- Cancel advantage on the save of one enemy versus the initial casting of a spell.
It takes one minute to complete the transformation of the crystal. You may not use this ability again until you finish a short or long rest. When you use this ability, any previous effects on any crystal end.
Aggressive Spell Vessel
Starting at 14th level, you’ve learned to channel the magic of others into your crystal foci. If you don’t know Counterspell and Dispel Magic, they are added to your spell list. If you succeed at dispelling or countering another caster’s spell in this manner while holding a crystal focus, some of the energy is then stored in your crystal for later use. The energy thus stored will allow you to cast one spell of half the level (rounded up) of the spell countered or dispelled without expending a spell slot as long as you are holding that crystal. The spell energy fades if you don’t use it within 24 hours, if you use this ability again (with any crystal), or if you use the same crystal for Crystal Spell Vessel (see above).
