When this item is broken, it has a 10*1/10 (10%) chance to drop the Arkhalis rather than an Enchanted Sword. This background object has a 33.33*1/3 (33.33%) chance to contain a 'true' breakable sword item rather than a discolored 'false' sword. On Old Chinese and tModLoader Legacy, it is obtainable from the unique background object found in an Enchanted Sword Shrine or very rarely in the Caverns layer. It has a weaker variant known as the Terragrim, which replaces it as a potential drop from Enchanted Sword Shrines. On PC, Console, Mobile, and tModLoader, it is part of Arkhalis' set, and is only obtainable through Hardmode Treasure Bags in Expert Mode. This damaging area has a rather wide spread, even attacking behind the player for a very short distance. Anything within this area takes constant damage at a rate far exceeding the weapon's stated use time. Instead of an overhead broadsword swing or a shortsword stab, the Arkhalis autoswings and appears as a series of blurred slashes aimed in the direction of the cursor. The Arkhalis is a rare melee weapon that appears to be a sword, but does not present an actual blade when used. Crissaegrim is Arkhayla's favorite sword, and her namesake weapon's appearance and function are modeled after it.For the weapon that replaced the Arkhalis in Sword Shrines in 1.4, see Terragrim. Its tooltip, 'I didn't get this off of a Schmoo', refers to the means of obtaining a Crissaegrim in Castlevania: Symphony of the Night. The weapon is named for Arkhayla, a former Quality Director at Re-Logic.While this method may be considered cheating by most, it can be useful for some players. Since the presence of the Arkhalis is determined when the sword-sprite is broken, it is possible to force its appearance by 'save scumming': Having found an Enchanted Sword Shrine with a 'real' sword-sprite, switch autosave off, and then keep breaking the sprite and force-quitting Terraria until you get an Arkhalis instead of an Enchanted Sword.

Despite there being more sword shrines in large worlds, it is easier to find them in medium worlds due to there being less space in between each shrine.

The best world size for finding the Arkhalis is medium, due to there being 1 sword shrine in small worlds, 3 in medium worlds, and 4 in large worlds.

Utilizing the fast speed of the Arkhalis combined with its small knockback, you can easily stun-lock enemies like the Unicorn.

Consider using a Ruthless Modifier for pre-hardmode enemies, and Godly or Demonic for hardmode enemies.

You should balance knockback on this weapon, to keep enemies inside the damage zone.

Because of its high attack speed and its ability to hit everything around the player, it can hit any projectile that can be destroyed before it reaches the player, making it fairly useful against the Goblin Sorcerer and Goblin Summoner's Chaos Balls and any other enemy with destructible projectiles.

Though its base damage is low, its high attack speed and multiple attacks per hit make it effective well into Hardmode.

The Arkhalis emits a large amount of white light-emitting particles for a short distance, making it useful for peeking through cave walls.

Both modifiers increase its average damage output by the same amount. The Arkhalis's unique means of attack is unaffected by any size and speed modifiers. Instead of an overhead broadsword swing or a shortsword stab, the Arkhalis appears as a series of blurred slashes aimed in the direction of the cursor. The Arkhalis autoswings, though it does not present an actual blade when used. The sword that the item gives is determined at the time the background object is broken, so there is no way to determine which sword the player will be given.

This means that on average, the chance of an Enchanted Sword Shrine dropping an Arkhalis is 1/30. When this item is broken, it has a 10% (1 in 10) chance to drop the Arkhalis rather than an Enchanted Sword. This background object has a 33% (1 in 3) chance to contain a 'true' breakable sword item rather than a discolored 'false' sword. It is quite rare, only obtainable from the unique background object found in an Enchanted Sword Shrine or very rarely in the Caverns layer. The Arkhalis is a rare melee weapon that appears to be a sword, but behaves unlike any other weapon.
