Hieroglyphic Seeker

You have spent the last few years reading dusty books about ancient civilizations. Your father has taught you to write runes. Maybe almost extinct nomadic tribe has appointed you as its confidant. You are about to embark on your first and greatest adventure, to uncover answers to questions asked by generations and discover whole nations lost in the history. Remember. The end of an adventure is beginning of another.

Forgotten Technology

At 3rd level, you have managed to find and copy an artifact of ancient civilization. You learn a singe Artificer Infusion and can infuse one item at a time. You can replace infusion you know with another one every time you got a level in this class. Prerequisites for you infusion that mentions Artificer level means Ranger level for you. 

The number of infusions known, and items that could be infused increase by one when you reach 11th level in this class.

Scripts Reader

At 3rd level, written words can no longer hide their meanings from you. If you can see a text that was written in a language that you don’t know, but in alphabet you know, you can distinguish with words are verbs and nouns. Dungeon Master can also tell you with words are proper nouns (names of places, people, events etc.).

Also at 3rd level, you become proficient in your choice of one of the following skills: History, Arcana or Religion. If you were already proficient, you double the proficiency instead.

Autopsy

Starting at 3rd level, you became skilled at examining bones and corpses. You know the cause of death of creature that remnants you found, and you know how much time have passed since it died. Sample causes are: wounded by piercing weapon, burned, poisoned, starved. If it has passed recently, the cause of death can be more precise.

Evasion

Beginning at 7th level, you can nimbly dodge out of the way of certain area effects, such as a red dragon's fiery breath or an Ice Storm spell. When you are subjected to an effect that allows you to make a Dexterity saving throw to take only half damage, you instead take no damage if you succeed on the saving throw, and only half damage if you fail.

Magic Scripts

At 11th level, you can always tell if any text is a Spell Scroll or magical in other way. If a text is a Spell Scroll written in a language that you don’t know, but in alphabet you know, you can still use it. You can also make a free copies of a Spell Scroll, but using such a copy will consume the original text and all of its copies. Using an original will consume all of its copies too. Additionally you can cast spells from scrolls from other classes spell list.

Spell Scroll Caster

When you reach 15th level, you mastered all ways to use Spell Scrolls. You do not need to roll to check if casting your spell was successful when the spell level is highest than the highest spell you know. Furthermore if your Game Master allows optional rule from “Xanathar's Guide to Everything“ about Spell Scroll creation, you and your allies can create Spell Scrolls faster: one hour per spell level, and cheaper: 25gp per spell level.
