The Isle Patch 0.21.720 Notes (3rd July 2026)
Kentrosaurus joins the roster with defensive mechanics and reflection damage. The Isle 0.21.720 also brings new biomes and a major skin system overhaul.

The Isle's 0.21.720 patch is now live on the Evrima Public Branch, rolling out following the recent Hordetest. Kentrosaurus is a defensive-focused herbivore that changes how you approach combat through reflection damage and a toggleable Defensive Stance.
Kentrosaurus rewards positioning and patience. Its passive reflects damage back to attackers who strike its tail or shoulder spikes, and activating Defensive Stance amplifies that reflection while blocking certain abilities entirely if they connect with those spikes. It's a kit built around making aggressors regret their approach, which should shake up the current meta for both predators and other herbivores.
Beyond the new dinosaur, Redwoods and Mangroves arrive as work-in-progress locations with supporting migration zones, plus additional human spawn points scattered across the map. The patch also tackles a backlog of animation, collision, and behaviour fixes. From correcting pteranodon weight and speed to preventing eggs from sitting unhatched indefinitely and fixing latched pouncers not detecting foliage properly. The full list, including fixes for Triceratops material swaps and Tyrannosaurus drinking animations, is below.
