Tips

 * Because Ice Tortoises emit a fair amount of light, they are comparably easy to spot. This also helps in revealing unexplored caves.
 * While 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 cannot 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 auto-swing weapon or can easily take it out. When attacking with melee weapons, using a weapon with high knockback will help keep it away.
 * Giant Tortoises and Ice Tortoises cannot drop through platforms. If you set up platforms along a underground Ice biome you can essentially farm them at ease.
