Terragrim

Holding the button pours out a continuous blur of slashes aimed at your cursor, and anything standing inside that area is hit far more often than the listed use time suggests. The reason is that it runs on global invincibility frames rather than normal weapon timing, so the real connection rate is fixed no matter what you do to the weapon. Size and speed reforges are ignored outright, which leaves Godly and Demonic tied as the best rolls since only raw damage and critical chance are still on the table. Even an editor-forced Legendary changes nothing about the swing. The slash field also reaches a short way behind you, which is worth remembering when something has gotten onto your back.

The sword stuck in stone at an Enchanted Sword Shrine is a background object, not furniture. Break it and it usually gives up an ordinary Enchanted Sword; occasionally this drops instead. The same object also generates rarely out in the open caverns, so the shrine is the reliable place to look but not the only one. Swords placed by the Rubblemaker look identical and will never roll it. Medium worlds are the better hunt: large worlds average more shrines but scatter them far enough apart that the extra attempts cost you more walking than they return. In Celebration Mk 10 and Zenith worlds you can skip all of that and buy one from the Princess during a Blood Moon.

The outcome is decided at the moment the object breaks, not when the world generated, and that leaves a hole open. Switch autosave off, break the sword, and if the wrong one falls out, close the application outright instead of exiting through the pause menu. Reload and swing again. Repeat until it lands.

The hit rate makes the second phase of the Brain of Cthulhu close to free. Plant yourself in the swarm, hold the button, and the creepers die before they can circle back around, so you can stand still and take almost nothing. It lights the area while swung and throws off light-emitting particles toward your aim, which is a small comfort underground.

The Arkhalis is the same weapon with better numbers and is the natural upgrade. The two swapped roles in 1.4: the Arkhalis moved into a developer set and this took over the shrine slot. Both borrow their look and their machine-gun slash from the Crissaegrim in Castlevania: Symphony of the Night, and the name is a play on it. It is one of a small handful of weapons you can find as a physical object placed in the world rather than in a chest or on a corpse, and it shows up in the Zenith attack animation despite not being one of its ingredients.
