Dungeons and Dragons 5e characters with high Intelligence gain analytical reasoning, strong memory, and effective fact-finding abilities. Intelligence directly supports spellcasting for Artificers and Wizards, and enhances Fighters choosing the Eldritch Knight subclass. Key skill knowledge tied to Intelligence includes Arcana, History, Investigation, Nature, and Religion, improving spell identification, clue deduction, and understanding natural and religious domains. The material also outlines a nonstandard play approach using high INT for tactical Battle Master Fighters, leveraging checks and roleplay for battlefield control and strategic advantages.

5e classes that use intelligence Dnd 5e classes that use intelligence . 5e intelligence classes . Dnd classes that use intelligence . Last Updated: April 8, 2022Intelligence measures a character’s analytical ability, their memory, and their ability to reason logically. A character with high Intelligence knows many facts and pieces of trivia, can estimate the value of items, can communicate nonverbally, and they are often good at puzzles, games of skill, researching, investigation, forgery, and investigation.Intelligence is most important for Artificers, for Wizards, and for Fighters who select the Eldritch Knight subclass. For those characters, Intelligence will make their spellcasting more effective.Arcana, History, Investigation, Nature, and Religion are all tied to Intelligence.Arcana measures knowledge of magic and how it works, magical symbols and traditions, and other planes of existence and their inhabitants.Arcana also allows characters to identify spells as they are being cast, which can be helpful for characters who can cast counterspell, for responding to the effects of spells with ongoing effects like illusions, and for handling spells without obvious visual effects like curses. Identifying spells using Arcana is explained in detail in Xanathar’s Guide to Everything.HistoryHistory measures your knowledge of the past: wars both recent and ancient, lost kingdoms, ancient lore, and all manner of events which took place in the past.Investigation is used to search for clues, and to make deductions based on those clues. Investigation can be used to search documents for a piece of information, to determine where someone has been based on the state of their clothing, or to perform other acts of deductive reasoning like identifying some types of illusions.Nature measures knowledge of the natural world; plants, animals, geography, terrain, weather, and natural cycles like tides and seasons.Religion measures knowledge of deities, rites, prayers, religious orders and their organizations and activities, holy symbols, and other topics related to religion. <<< Previous Page Next Page >>> Disclaimer : this answer presents you with one option, but there are other (maybe better) possiblities. This option requires DM collaboration, as it's a non-standard way of playing. Your goal is to play a character who focuses on Intelligence without being an actual spellcaster. A high Intelligence, when not used for spellcasting, gives better Investigation, History, Nature, Arcana and Religion checks (and better Intelligence saving throws, but these are rather rare) . It also gives a better chance to remember details from previous sessions ( "Memory" checks) . Your goal is to have a more-than-roleplay-only purpose, so you probably want to make a use of these skills for combat-related purposes. In other words, you want a mechanical, non-magical advantage to having a high INT score. So, of the 12 classes, we can eliminate those with spellcasting or other supernatural power : Bards, Clerics, Druids, Paladins, Rangers, Sorcerers, Warlocks and Wizards. We can also eliminate Barbarians, whose general playstyle is often considered "mindless", especially when they rage. Monks can be discarded as well, as they mainly focus on the Wisdom mental ability, which is not what you seek there. This leaves us with Fighters and Rogues. Another answer already focuses on Rogue archetypes that would fit your needs, so let's focus on Fighters here. I am aware that Fighters in general don't have class features that use Intelligence per say. However, Fighters, unlike Barbarians, focus on tactics more than brute strength to win fights, and as explained below, a good Intelligence can give you better tactics, thus befitting the class's efficiency. There are currently 7 Fighter Archetypes : Champion, Battle Master, Eldritch Knight, Purple Dragon Knight, Arcane Archer, Cavalier and Samurai.
