Terragrim

The Terragrim is a rare pre-Hardmode melee weapon that appears to be a sword, but does not present an actual blade when used. Instead of an overhead broadsword swing or a shortsword stab, the Terragrim autoswings and appears as a series of blurred slashes aimed in the direction of the cursor. Anything within this area takes constant damage at a rate far exceeding the weapon's stated use time. This damaging area has a rather wide spread, even attacking behind the player for a very short distance.

It is obtainable from the unique background object found in an Enchanted Sword Shrine or very rarely in the Caverns layer. When the object is destroyed, it has a chance to drop a Terragrim rather than an Enchanted Sword. Additionally, it can be purchased from the Princess in the secret seed celebrationmk10 for during a Blood Moon.

The Terragrim's unique means of attack is unaffected by any size and speed modifiers.

Note that this and Arkhalis are the only swords unable to obtain the Legendary modifier.

Tips

 * Its speed makes it very easy to defeat the Brain of Cthulhu's second phase, allowing the user to stand still and avoid taking damage.
 * It is also very effective at defeating the Eater of Worlds as well due to its high attack speed and damage. It is able to hit up to three segments of the Eater at once.

Trivia

 * The Terragrim's name is a reference to the Crissaegrim, also known as Valmanway, from the platform-adventure action role-playing game . Like the Arkhalis, the Terragrim's function and appearance are also based off of the Valmanway.
 * The Terragrim appears in the Zenith's animation despite it not being used to craft the Zenith.
 * The Terragrim replaced the Arkhalis as a special weapon found in Enchanted Sword Shrines, as the Arkhalis is found in Arkhalis's developer set as of 1.4.0.1.
 * Even if using an inventory editor to obtain the Legendary modifier, it will not change how fast the sword slashes or how large the slashes are.
