Hama no Tsurugi (5e Equipment)
From D&D Wiki
Weapon (Greatsword), artifact (Requires attunement.)
The Hama no Tsurugi is a legendary sword with +3 to attack and damage rolls. Belonging to a princess from a certain country, the princess had the power to nullify all magic, and this artifact made such ability even stronger. The sword could destroy any type of summoned being with one hit, it could also defend against magical effects (the princess used to rely on this power for defense before she mastered her own powers, but this isn't a perfect power) and it also could be used to attack at a long distance, so any summoned creature or object created by magic can be destroyed by this sword even at a distance. The sword is also known to be extremely deadly to casters since it's power destroys magic any being that uses magic suffer great damage from this blade when hit since it destroys the arcane energy inside the target.
Vorpal Sword When you attack a creature that has at least one head with this weapon and roll a 20 on the attack roll, you cut off one of the creature’s heads. The creature dies if it can’t survive without the lost head. A creature is immune to this effect if it is immune to slashing damage, doesn’t have or need a head, has legendary actions, or the GM decides that the creature is too big for its head to be cut off with this weapon. Such a creature instead takes an extra 6d8 slashing damage from the hit.
The Supreme Sword The Hama no Tsurugi deals 2d10 slashing damage, instead of the normal 2d6 from a greatsword.
Destroyer of Summoned Existence Can destroy anything brought to existence from magic, from summoned creatures to things like earth pillars and fire walls, this power has a range of 90ft, but only against summoned objects, to dispel a summoned creature, it must be hit directly by the blade.
