Class is the first major build decision in D&D. It determines hit points, saving throws, core proficiencies, class features, spellcasting access, and when the character starts to specialize through subclass choice. Most of the rest of character creation makes more sense once class is settled first.

Class defines the chassis. It tells you what the character is expected to do reliably before items, feats, or clever tactics enter the picture.
Read for role, not just flavor. Hit die, proficiencies, spellcasting, and subclass level often matter more in practice than class fantasy copy.

Hit points and survivability. The class sets your hit die and influences how much risk the character can absorb before the fight turns ugly.

Saving throws and proficiencies. These define both defense and competency. They tell you what the character resists well and what tools or weapons they can actually use.

Skill choices and build direction. A class often signals what kinds of scenes the character is expected to contribute to even before background and species are layered in.

Spellcasting access and subclass timing. Many classes either open a full magical lane or establish when a later specialization changes the character’s role.

What score does this class actually want?

Look at the class’s core actions first, then confirm your ability scores and background support that plan.

When does the class specialize?

Subclass timing matters because it tells you when a broad class identity narrows into a more specific play pattern.

Is this class front-line, support, or control?

Even flavorful classes still need a table function. Identify that early and the rest of the build gets easier.

What does this class need from gear?

Armor, weapons, focuses, and tools often reveal whether the class plan is actually practical at level 1.

Start with the chassis. Hit die, armor, weapons, saving throws, skills, spellcasting, and starting equipment determine how the class survives level 1.

Then read the loop. Identify what the class expects to do on a normal turn before looking for rare, flashy, or late-level options.

Finally read the growth. Subclass timing, resource scaling, extra attacks, spell levels, and feature cadence show how the character changes over a campaign.
