Archivist Class Features

As a full caster the Archivist has relatively few class features. The Archivist has d6 HP, 2+int Skill Points and ½ BAB. His Class Skills are Appraise (Int), Craft (Int), Fly (Dex), Knowledge (arcana) (Int), Knowledge (history) (Int), Knowledge (nature) (Int), Knowledge (planes) (Int), Linguistics (Int), Perception (Wis), Profession (Wis), Sense Motive (Wis), Spellcraft (Int), and Use Magic Device (Cha).

At first level the Archivist gains his Rune Magic, his first bonus feat chosen from a Rune Casting focused list and has to choose a specialization called a Study.
A Study is the specialization class feature of the Archivist, giving the them additional abilities at specific levels, as well as an additional bonus when overloading a Script with the right type of Runic Charge. Besides the six Studies for each of the six Designs there are 12 more specialized Study options available in the 3rd chapter.

Altered Script is gained at fourth level, allowing the Archivist to change the Design of their Runic Charges once per day.
More bonus feats, Study abilities and Altered Script uses come one by one every two levels. The capstone at level 20 is a final Study ability.

In short the class features of the Archivist can be summed up as ‘Wizard, but Rune Casting’. Most of the build choices comes from what you want to do as caster, with each Design heaving its own specialization.

The dungeon has lines of meaningless text blocking some of the corridors. Anyone going over the lines is forced to make a Will save or temporary become unable to read, as well as losing 1d6 random Runic Charges.

Runecharged Amulet, 250 gp.
This clay amulet is inscribed with runes and holds a single runic charge of a specific Design.
A Scribe can use this Runic Charge with any abilities that use runic charges or to overload a script.  The runic charge within the amulet does not count against its users normal maximum of runic charges he can maintain at once based on his scribe level.
The scribe still cannot overload more charges into a given script than his normal maximum. If he has more runic charges available than his normal maximum, he chooses which of the ones available to him are overloaded into the script. He does not have to use the charge in the amulet if does not wish to, but must otherwise overload as many charges he can as normal.
To randomly determine what runic charge design is in the amulet, roll on the following table:
d% Charge Type
01–16 Alteration
17–33 Creation
34–50 Destruction
51–67 Invocation
68–84 Manipulation
85–100 Revelation
