Archivist

Though most investigators fill their grimoires
with hard-won knowledge borne from encounters
with the supernatural threats, some prefer to
do bookkeeping instead. Such archivists accrue
knowledge, not trinkets, by spending untold hours
digging through disparate tomes of occult knowledge
and compiling them into encyclopedic texts on the
supernatural. Through their research, archivists
become academic masters of the arcane, and
priceless reservoirs of obscure knowledge.
TRINKET
Starting when you choose this specialization at 3rd
level, you’ve collected a powerful trinket to enhance
your ritual magic:
Archaic Scroll. You can perform a ritual
spell with your Rushed Incantation feature without
expending one of the feature’s uses.
THESIS
Also at 3rd level, you gain access to certain spells
associated with your thesis. Pick one of the following
subject areas for your thesis: Corpus, Ignis, Mortis,
or Regis. You gain a list of associated thesis spells.
Once you gain access to a thesis spell, it is added
to your grimoire. If you gain access to a spell that
doesn’t appear on the investigator ritual list, the spell
is nonetheless an investigator spell for you. You can
use your action and expend a use of your Rushed
Incantation feature to cast one of your thesis spells.

ERUDITE SPELL
By 6th level, you’ve mastered the difficult theory
behind arcane propagation. When you cast a spell
which forces a creature to make a saving throw to
resist its effects, you can give one target of the spell
disadvantage on its first saving throw against the
spell.
Once you use this ability, you can’t use it again
until you finish a short or long rest.
ENCYCLOPEDIC EXPERTISE
Starting at 10th level, you can identify any arcane
effect from memory. Whenever you witness a spell
being cast or investigate a magical effect, you can
always identify the spell that was cast, the magic
item responsible, or the monster which produced the
effect. However, this ability fails to identify spells,
magic items, and monsters which are utterly unique
or are otherwise not recorded in arcane texts.
EIDETIC MEMORY
At 14th level, you can effortlessly duplicate spells you
see in the world. You can copy any ritual spell you
see being cast into your grimoire.
Moreover, you can precisely copy the exact
motions of a spell’s casting to duplicate its effect.
When you see a spell of 5th level or lower being cast,
you can use your action and spend 1 use of your
Rushed Incantation feature as an action to cast the
spell yourself without spending a spell slot. The spell
must have a casting time of 1 action, must not have
expensive spell components, and must have taken
place within the last minute to use this ability.
Once you duplicate a spell in this way, you can’t
duplicate it again until you finish a long rest.
