Rules edition: This tactics guide uses the 2014 Fighter and the legacy Gnome traits from the 2014 Player’s Handbook. It focuses on combat decisions, not a full character build; see the Gnome Fighter build guide for ability scores and character options.
What a Small fighter can—and cannot—do
A Gnome Fighter is not less durable because of size: the 2014 Fighter uses a d10 Hit Die, just like every other Fighter. The genuine trade-offs are more specific. A legacy Gnome is Small, walks 25 feet, and has a +2 Intelligence increase (plus a subrace increase); none of those traits grants Strength or Dexterity by default. Optional origin customization can change ability increases, but it does not change the weapon rules.
The important restriction is the Heavy weapon property. A Small creature has disadvantage on attack rolls with a Heavy weapon, so a greatsword, glaive, longbow, or heavy crossbow is usually a poor choice unless a specific effect changes the character’s size or the table uses a house rule. High Strength does not remove that disadvantage. A rapier, longsword used one-handed, spear, or shortbow can be a practical alternative, depending on whether the character prioritizes Dexterity, a shield, or reach.
Plan around real cover and clear lanes
Small size does not automatically provide better hiding, cover, or access through enemy spaces. Cover depends on what physically blocks the attack: half cover grants a +2 bonus to AC and Dexterity saving throws, three-quarters cover grants +5, and total cover prevents direct targeting. Ask the DM how a wall, pillar, creature, or piece of terrain affects the line between attacker and target; simply standing beside a Medium ally does not guarantee cover.
You can move through the space of a nonhostile creature, but you cannot end your move there. An enemy’s space is different: you can pass through it only if that enemy is at least two size categories larger or smaller than you. A Medium opponent is only one category larger than a Small Gnome, so it blocks that route. If a passage is tight enough to require squeezing, the normal costs still apply: each foot takes an extra foot of movement, your attacks and Dexterity saves have disadvantage, and attacks against you have advantage. Treat a narrow gap as an emergency route, not a free flanking trick.
Make the 25-foot speed count
Choose a starting position with a useful lane to your priority target, then use movement deliberately. The 2014 combat rules let you split movement around an action and between attacks in an Attack action. At Fighter level 5, for example, you can move to a clear angle, make one attack, reposition, then make the second. You do not need a speed-boosting feat to use that flexibility; just track the movement you have left and avoid crossing threatened spaces casually.
Archery is still a sound Fighting Style for a Gnome: it does not require a racial Dexterity bonus, and its +2 applies to ranged weapon attack rolls. If you prefer a shield and a one-handed weapon, Dueling can add damage while you wield that weapon in one hand and no other weapon. Defense is another straightforward option while wearing armor. These choices depend on your preferred tactics, not on a special size-based penalty to hit points or damage.
Use Gnome Cunning as a defense, not a guarantee
Gnome Cunning gives advantage on Intelligence, Wisdom, and Charisma saving throws against magic. It can make a Gnome Fighter harder to disable with some spells, but it is not blanket magic resistance: it does not apply to Strength, Dexterity, or Constitution saves, and it does not protect against every magical effect. Advantage also does not stack with itself. When an enemy caster appears, identify the likely saving throw and keep an escape route or ally support in mind instead of assuming the Gnome can ignore the spell.
Forest Gnomes know the Minor Illusion cantrip, which can create a sound or a static image of an object within the spell’s limits. It does not create physical cover, conceal a creature automatically, or force an enemy to spend an action investigating. A convincing decoy may still support a plan when the DM agrees that the situation makes sense, but treat the spell as a creative tool rather than a guaranteed combat condition. Rock Gnome traits lean more toward durability and tinkering; neither subrace grants a general Stealth bonus.
Coordinate your Fighter features
Fighter features reward planning your turn. Action Surge gives you one additional action, so save it for a moment when a second Attack action, Dash, Disengage, or other action can change the encounter—not just for a small damage increase. Extra Attack applies when you take the Attack action; it does not turn every action into multiple attacks. If you choose a spellcasting or maneuver subclass, follow that feature’s own action, target, and ability-score rules rather than assuming Intelligence powers all Gnome-friendly tactics.
For example, a Battle Master can use a maneuver when its trigger and requirements fit the situation; an Eldritch Knight’s spell choices still compete with the limits of its spellcasting feature. Gnome Cunning complements either concept defensively, but does not improve a maneuver’s save DC or a Fighter’s weapon attacks. For a full build, subclass comparison, and level-by-level options, use the linked build guide rather than treating one subclass as mandatory.
Quick tactical checklist
- Choose a non-Heavy weapon if you want to avoid the Small-creature attack disadvantage.
- Use actual terrain for cover; size alone does not grant a hiding or AC bonus.
- Move through allies when useful, but do not expect to pass through an ordinary Medium enemy.
- Track your 25-foot speed, threatened spaces, and movement between attacks.
- Apply Gnome Cunning only to the three mental saves it names and only against magic.
- Use Minor Illusion for plausible sounds or images, not as automatic concealment or cover.
