Tick
A slow, armored hunter that turns the tall grass into a deadly ambush zone.
Tick is a large, arthropod-like boss that stalks the tall grasses of the Grasslands biome in Risk of Rain 2. Resembling an oversized, multi-legged tick with a bulbous carapace, it is one of the more visually distinctive mid-tier bosses survivors will encounter during their descent through the alien world's biomes.
Rather than a fast, frenzied combatant, Tick relies on its sheer bulk, a punishing charge, and a slow but relentless advance to close the distance on survivors. It represents the kind of grounded, heavy threat that forces players to manage positioning and cooldowns carefully, especially in the early-to-mid stages of a run when gear is still limited.

Lore & Background
In the ecology of the alien world, Tick occupies the niche of a heavy, patient predator. Where smaller creatures dart and swarm, Tick simply waits beneath the canopy of grass until a survivor stumbles close enough to trigger its predatory instincts. Its thick, segmented carapace and broad, jointed legs are built for a single purpose: to pin down prey and grind through whatever armor stands between its mandibles and the flesh beneath.
Field reports from surviving expedition teams describe Tick as almost ceremonial in its aggression—it does not lunge or shriek. It simply turns, lowers its bulk, and drives forward in a slow, inexorable charge that can flatten cover and knock survivors off their feet. Once a survivor is in range, Tick's mandibles snap with a sickening crunch, and small, viscous projectiles are spat from its maw, leaving lingering damage on the ground.
Fans of the series often note that Tick's design feels deliberately 'old-world' compared to the more alien horrors of later biomes. It is a creature that could belong to any overgrown, forgotten ecosystem, and that grounded menace makes it all the more unsettling when it barrels through the grass with the weight of a small vehicle.
In Their Own Story
The grass was waist-high and swaying in a wind that smelled of copper and wet soil. The team had been pushing through the Grasslands for what felt like an hour, the canopy blocking all line of sight to the sky. Then the grass stopped moving. Not the wind—the grass itself, as if something vast had pressed down and held still.
A carapace the color of dried blood rose slowly from the tall stalks, segmented and glistening. Six legs, each thicker than a survivor's torso, gripped the earth. The thing turned its bulbous head, and two dim, ancient eyes found the nearest straggler.
It didn't roar. It didn't need to. The ground trembled once, twice, and then the grass parted in a wide, slow furrow as Tick drove forward, mandibles clicking open, the air filling with the wet sound of something spitting acid into the dirt. The straggler was gone before the second charge landed. The rest of the team ran, but the grass was everywhere, and Tick was patient, and the wind kept blowing the scent of them right back into its jaws.
Reader's Guide
Name: Tick Role in the run: Mid-tier boss encountered in the Grasslands biome. Tick serves as a pacing checkpoint, testing whether the team can handle a slow, high-health target before the run escalates into more chaotic enemy density.
Key abilities / attack patterns: - Slow Advance: Tick moves at a deliberate, grinding pace toward the nearest survivor, making it hard to kite indefinitely. - Charge: After a brief tell (a low crouch and a grinding sound), Tick lunges forward in a straight line, dealing heavy damage and knocking survivors down. This is its primary burst threat. - Acid Spit: At medium range, Tick spits small viscous projectiles that leave lingering damage patches on the ground, punishing players who camp in one spot. - Mandible Snap: At close range, Tick delivers a quick, high-damage bite. Multiple survivors can be hit in a single swing.
First appearance biome: Grasslands.
Lore connections: Tick's design echoes the 'grounded predator' archetype of the early biomes, contrasting with the more surreal horrors of later zones. Its presence reinforces the idea that the alien world has a full, layered food chain.
Threat level: Boss-tier. Tick is tanky and can one-shot undergeared survivors with its charge or bite. In a long run with heavy gear, it becomes a manageable loot source; in an early run, it is a genuine wipe risk.
How to counter: Maintain lateral movement to avoid the charge's straight-line path. Use AoE damage (fire, lightning, explosions) to chip its health from range. Watch for the crouch tell before the charge and sidestep. Avoid standing in acid pools. Focus fire during its recovery windows between attacks. In a team, assign one player to kite while others deal damage.
Did You Know?
- Tick's charge attack travels in a perfectly straight line, meaning a single well-timed lateral dash can completely negate its most dangerous move.
- Despite its slow movement, Tick's health pool scales with the run's duration, making it significantly more dangerous in a 30+ minute run than in a quick 10-minute one.
- Tick's acid spit leaves ground damage that persists for several seconds, creating small 'hazard zones' that can chain-hit survivors who try to camp in the same spot.
- In the Grasslands biome, Tick's tall-grass camouflage makes it easy to walk directly into its range before its first attack, catching unprepared teams off guard.
