# Background
Every story has a beginning. Your character's background reveals where you came from, how you became an adventurer, and your place in the world. Choosing a background provides you with important story cues about your character's identity. [[SRD p60](https://media.wizards.com/2016/downloads/DND/SRD-OGL_V5.1.pdf#page=60)]
_Note:_ acolyte is the only background included in the SRD.
# Class
A character class is a fundamental part of the identity and nature of
characters in the Dungeons & Dragons role-playing game. A character's
capabilities, strengths, and weaknesses are largely defined by its class.
A character's class affects a character's available skills and abilities. [[SRD p8-55](https://media.wizards.com/2016/downloads/DND/SRD-OGL_V5.1.pdf#page=8)]
# Condition
A condition alters a creature’s capabilities in a variety of ways and can
arise as a result of a spell, a class feature, a monster’s attack, or other
effect. Most conditions, such as blinded, are impairments, but a few, such
as invisible, can be advantageous.
# Damage type
Different attacks, damaging spells, and other harmful effects deal different
types of damage. Damage types have no rules of their own, but other rules,
such as damage resistance, rely on the types.
# Feature
When you gain a new level in a class, you get its features for that level.
You don’t, however, receive the class’s starting Equipment, and a few
features have additional rules when you’re multiclassing: Channel Divinity,
Extra Attack, Unarmored Defense, and Spellcasting.
# Language
Your race indicates the languages your character can speak by default, and your background might give you access to one or more additional languages of your choice. [[SRD p59](https://media.wizards.com/2016/downloads/DND/SRD-OGL_V5.1.pdf#page=59)]
# Magic School
Academies of magic group spells into eight categories called schools of
magic. Scholars, particularly wizards, apply these categories to all spells,
believing that all magic functions in essentially the same way, whether it
derives from rigorous study or is bestowed by a deity.
# Proficiency
By virtue of race, class, and background a character is proficient at using certain skills, weapons, and equipment. Characters can also gain additional proficiencies at higher levels or by multiclassing. A characters starting proficiencies are determined during character creation.
# Rule
Rules are pages in the SRD that document the mechanics of Dungeons and Dragons.
Rules have descriptions which is the text directly underneath the rule heading
in the SRD. Rules also have subsections for each heading underneath the rule in the SRD.
# Skill
Each ability covers a broad range of capabilities, including skills that a character or a monster can be proficient in. A skill represents a specific aspect of an ability score, and an individual's proficiency in a skill demonstrates a focus on that aspect. [[SRD p77](https://media.wizards.com/2016/downloads/DND/SRD-OGL_V5.1.pdf#page=77)]
# Ability Score
Represents one of the six abilities that describes a creature's physical and mental characteristics. The three main rolls of the game - the ability check, the saving throw, and the attack roll - rely on the ability scores. [[SRD p76](https://media.wizards.com/2016/downloads/DND/SRD-OGL_V5.1.pdf#page=76)]
# Alignment
A typical creature in the game world has an alignment, which broadly describes its moral and personal attitudes. Alignment is a combination of two factors: one identifies morality (good, evil, or neutral), and the other describes attitudes toward society and order (lawful, chaotic, or neutral). Thus, nine distinct alignments define the possible combinations.[[SRD p58](https://media.wizards.com/2016/downloads/DND/SRD-OGL_V5.1.pdf#page=58)]
# Equipment
Opportunities abound to find treasure, equipment, weapons, armor, and more
in the dungeons you explore. Normally, you can sell your treasures and
trinkets when you return to a town or other settlement, provided that you
can find buyers and merchants interested in your loot.
