Order of the memento

The astral plane is filled with memories of those known and unknown. Order of memento wizards use these memories for their own uses, sharing it or making it a burden for others.

Astral knowledge

At level 2, when you start a long rest, you can choose to have your thoughts enter the astral plane. When you do so, you can choose to expend hit dice equal to your proficiency bonus. When you do so, you do not roll them, but instead you choose a spell on the wizard spell list that is equal to or totaling the level of the spell (for example, you can get two first level spells or one second level spell with 2 hit dice. You then have the spell(s) added to your spell book and must make a constitution saving throw(DC=10+the level of all the spells obtained). If you fail, you cannot use this feature for 1d4 long rests. 

Bestow knowledge

At level 2, as an action, you can choose a number of willing creatures equal to your proficiency bonus and choose a number of spells in your spell book up to your proficiency bonus+your wizard level. These allies now know these spells for 1 hour, or until you choose to end it(no action required) or until they drop to 0hitpoints, if they have no caster level, they have a spell caster level equal to half your level(rounded up). Their spellcasting ability is their choice of intelligence, wisdom or charisma. You can no longer cast the spells you chose for your allies, but you regain them when the effect ends. You can use this feature once per long rest.

Burden from beyond

At level 6, as bonus action, you can choose a number of creatures equal to your proficiency bonus. They must make a intelligence, wisdom, or charisma saving throw (you must choose when you gain this feature). If they fail, they become cursed. The curse comes into effect whenever they cast a spell, when they cast a spell of 1st level or higher, they must roll a d20. If the roll is below or equal to your level, you must roll a d10 and consult the chart below. if the result is a spell, it requires no concentration and lasts for the full duration unless specified. after rolling on the chart, the creature can remake the saving throw to potentially end the effect. Otherwise the curse stays for 1 minute or until you choose to end it as a bonus action. If a creature attempts remove curse or other such spells, the curse is removed but the uncurser must make the saving throw or become cursed instead. You can use this feature a number of times equal to your proficiency bonus, regaining uses of this feature when you finish a short or long rest.

persistent knowledge

At level 10, The duration of your bestow knowledge feature is now equal to your proficiency bonus. In addition, when a creature affected by your bestow knowledge feature is knocked to 0 hit points, you can choose a willing creature within 60ft of them to then receive the spells and thus be effected by the bestow knowledge feature, retaining the duration of the previous holder. You can use that part of the feature once per long rest.

Student’s knowledge

At level 14, When you reach 0 hit points but not killed outright, you can choose a willing creature affected by your bestow knowledge feature and have them go to 0 hit points and begin dying(persistent knowledge cannot be used). You then copy that creature’s statistics except for spellcasting (which is replaced by your own), features from this subclass, and your intelligence, wisdom, and charisma scores. This transformation lasts for 1 minute or until you reach 0 hit points. You cannot use this feature again until you finish 1d4 long rests.
