Mid Herbivore
Pachycephalosaurus
Pachycephalosaurus wyomingensis
“Thick-headed lizard from Wyoming”
First & only carrier of the Fracture Mechanic — bone-dome ram can cripple anything.
In The Isle
In Evrima, Pachycephalosaurus is the first and only animal with the **Fracture Mechanic** — a ram that can severely cripple any animal regardless of size. Utahraptors find Pachy very hard to kill: it directly counters the raptor's pounce and can drop one in 2 hits, making it nearly impossible for a solo raptor to bring down. Carnotaurus can kill a Pachy easily by ambush-charging it, but in a stamina fight Pachy out-stams the Carno and a skilled Pachy player can bring one down. Pachy's hard counter is water: it's one of the slowest swimmers in the game and has an oxygen span of under 10 seconds — getting grabbed by a Deinosuchus is an instant death sentence. Its preferred diet is **Oranges (carbs)**, **Agave (proteins)**, and **Coconuts (lipids)** — Horned Melons and Agave grow in plains and arid regions, Coconuts grow in plains and on the coast. Coconuts must be cracked open first: look down and press RMB twice to open one for eating. The roadmap framing: "Known not just for its headstrong attitude, but its literal dome-shaped skull — this thick-headed herbivore can cause quite the dent." Pachycephalosaurus was added in Patch 0.1.1.1531 and re-added to Evrima in Patch 0.8.60.19.
In Real Life
Pachycephalosaurus lived during the Late Cretaceous (Maastrichtian stage) in what is now North America, with remains excavated in Montana, South Dakota, and Wyoming. It was a herbivore primarily known from a single skull and a few extremely thick skull roofs, though more complete fossils have been found in recent years. Pachycephalosaurus was one of the last non-avian dinosaurs before the Cretaceous–Paleogene extinction event. The genera Tylosteus, Stygimoloch, and Dracorex have been synonymized with Pachycephalosaurus in some recent studies.
Abilities
- • Fracture Mechanic (Evrima) — ram can cripple any animal, regardless of size
- • Bone-dome ram attack — extremely high damage for size class
- • Direct counter to Utahraptor's pounce — drops a raptor in 2 hits
- • Can out-stamina Carnotaurus in extended fights
- • Very little fall damage (Legacy)
Strengths & Weaknesses
- + Highest stamina of all juveniles
- + Relatively strong juvenile stage
- + Decent health and mass for size
- + Extremely high damage for its size
- + Very little fall damage (Legacy)
- + Decent running speed (~42 km/h Adult)
- + High Fracture chance (Evrima) — single mechanic that punishes any opponent
- − Pathetic bleed resistance
- − Pathetic bleed heal
- − Surprisingly loud for its size
- − Not great in a sustained fight against carnivores — Utahraptor still kills in 5 bites and outpaces it
- − Long growth time for size class
- − Terrible in water — slow swim + <10s oxygen + easy Deino kill
Behavior
Pachy plays as a fracture artist — line up clean rams to cripple bigger targets, then either finish or disengage. Skilled Pachy players can solo apex carnivores by chaining fractures. Avoid water at all costs: poor swim speed + <10s oxygen + Deino lurking = instant kill.
Growth
Total ~2h 10min (130 min) Juvie → Adult — Hatch 20m, Juvie 70m, Adult 60m.
