Ice Tortoise

The Giant Ice Tortoise is a Hardmode mob that is found in the Underground Snow biome. It attacks by spinning inside its shell and jumping at the player. It can deal incredible contact damage and it flies with great accuracy, so one must take care when fighting them if they are not well equipped for their devastating assaults.

Strategy
When the Ice Tortoise hides in its shell, it will take very low 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. Good weapons for this include the Cutlass for Melee characters, the Laser Rifle or Golden Shower for Magic characters, or a Repeater for a Ranged character. Also, the Ice Tortoise does a considerable amount of damage, so it is recommended for Melee characters to use a weapon with high knockback.
