The 冰雪陆龟 is a 困难模式 敌怪 that is found in the 地下雪原 生物群落. It attacks by spinning inside its shell and jumping at the player, similarly to the 巨型陆龟 and 巨型卷壳怪. It flies with high speed and accuracy, and deals incredible contact 伤害, making it dangerous to deal with.
- When the Ice Tortoise hides in its shell, it takes very little damage. The quickest way to defeat it is to attack it continuously so it can't retreat into its shell. Furthermore, while it is stuck like this, it will be unable to jump at the player, making it easy to kill safely. Any rapid-firing weapon can easily take it out. When attacking with melee weapons, using a weapon with high knockback will help keep it away.
- Ice Tortoises emit a fair amount of light, making them easy to spot. This helps in revealing unexplored caverns.
