What is Giant Fly 5e?

The giant fly 5e, a larger relative of common flies, is an insectoid monstrosity that players encounter in the beloved role-playing game, Dungeons & Dragons 5th edition (D&D 5e).

What is Giant Fly 5e

Unlike their real-world counterparts, these colossal creatures are not easily overlooked. They measure several meters in size and bring noteworthy encounters to your D&D sessions.

In the world of D&D 5e, a Giant Fly’s physical strength far exceeds its mundane relatives.

While most flies pose little threat to adventurers and creatures alike, the Giant Fly stands out with its substantial power and unique abilities, which can sway the course of combat significantly.

Despite their intimidating presence and size, they maintain behaviors similar to ordinary flies buzzing around and being particularly drawn toward sources of waste or filth.

Navigating an encounter with a Giant Fly adds unanticipated dynamics and challenges to your gameplay.

It encourages strategic thinking as its attributes differ vastly from standard beasts encountered within the D&D universe.

Even seasoned players find surprises in encounters with these creatures due to their specialized skills in climbing, flying, and perceiving what’s around them.

Whether you meet them solitarily or come across a swarm, every run-in with a giant fly will enrich your D&D experience in unexpected ways.

Special Abilities

Just like the multitude of creatures that inhabit the Dungeons & Dragons world, the Giant Fly 5e possesses a distinctive special ability that sets it apart from others.

Special Abilities

Known as Filth Fever, this disease is transmitted through bite injury and introduces a realm of complexities for the attacked creature.

Specifically, once bitten, the opposing creature must save Fortitude DC 14- if failed, the onset of symptoms appears in 1 to 3 days.

The disease frequency stands at once per day inflicting between one to three units of damage on both dexterity and constitution each time it takes effect. Fortunately, two consecutive successful saves can cure this debilitating condition.

These elements introduce varied outcomes during encounters with a Giant Fly adding depth to your gaming sessions.


The mesmerizing world of Dungeons & Dragons thrives not just on ferocious battles but also on skills that creatures possess making for a strategic game.


The Giant Fly 5e has an arsenal of skills namely Climb, Fly, and Perception which make it more than just a formidable opponent on the battlefield.


One key skill that truly stands out is its climbing ability. While seemingly trivial for an insectoid creature given its flying capacity, its +9 climb rate is indeed noteworthy.

This equips them with an advantage in moving through terrain granting them increased movement flexibility thereby posing unexpected threats during scenarios with complex landscapes.


As expected from any fly species regardless of its size, flying is considered essential.

The giant fly boasts a +7 flying skill which enables not just locomotion but also empowers it with fluidity and finesse while maneuvering in the air.

This ability greatly augments their potential making them not only difficult to hit during combat but also particularly effective when launching sudden attacks or retreating from disadvantageous situations.


The value of perception cannot be overstressed in D&D as it considerably impacts battles and non-combat interactions.

In Giant Fly’s case, although modest, their +2 perception skill sharpens their awareness of the environment.

Whether detecting hidden opponents or perceiving imminent threats or opportunities, this skill does contribute to their survival and strategic elements offering unexpected challenges for players during encounters.

Pair: The Duos Of Danger

Your storytelling could involve a situation where a pair of these colossal insects exists together.

This presents teams with a distinctive challenge as they must now navigate encounters with pathfinding mechanisms to confront not one but two massive adversaries simultaneously.

This unique dynamic requires more teamwork and strategy among players and significantly escalates the thrill involved in gameplay.

Swarm: A Cloud of Buzzing Menace

Dungeons & Dragons 5e presents your characters with their ultimate test dealing with a Swarm.

Numbered anywhere between 3 to 12, handling these vast groups calls for understanding their collective behavior more deeply than merely fighting off individual insects.

Your gaming strategies must encompass tactics that could successfully dispel big clusters- like using area damage spells or traps to outwit them.

Resilience towards disease or poison spells is also essential when facing swarms of Giant Fly 5e due to their inherent ability to spread diseases.
