Ranger / FighterMulticlass Build Guide — D&D 5e

Ranger already has the Archery fighting style, the best flat accuracy bonus in 5e (+2 to ranged attack rolls). Fighter 1 adds a second style — Defense (+1 AC) is the standard, quietly raising a medium-armour ranger’s survivability without any ongoing cost. Second Wind adds a bonus-action self-heal, something the ranger otherwise has to spend a spell slot on.

Fighter 2 is the real prize: Action Surge. An extra action means two more ranged attacks, each triggering Hunter’s Mark. On round one, a Gloom Stalker ranger who Action Surges produces: two normal attacks, one Dread Ambusher bonus attack with +1d8, then two more attacks from Action Surge — five shots in a single round, each carrying Hunter’s Mark. That is the most devastating ranged alpha strike any martial can produce, and it recharges on a short rest.

The dip is shallow and painless because both classes share Strength and Dexterity as their multiclass ability requirements. There is no new stat to fund. The only cost is two levels of delayed ranger spell progression, which means your highest-level slots arrive two levels late. In a campaign that ends before 17th level, you will never miss those slots.

Ability priority: DEX → CON → WIS — Dexterity is your entire ranged engine. Constitution holds Hunter’s Mark concentration and benefits from the fighter’s CON save proficiency (if you start Fighter 1). Wisdom is for spell save DCs, which most ranger spells do not rely on.
