Legion Sestar (5e Equipment)
From D&D Wiki
Martial Melee Weapons
An uncommon weapon that combines both a longsword and a glaive into one. The hybrid weapon allows the wielder to use this weapon as a glaive with reach or as a longsword that requires two-hands because of the weight.
As a bonus action, the blade of the longsword can be detached and swung around on the large through the click of a switch on the large, circle hand guard, turning the weapon into a glaive. In glaive form, the Legion Sestar receives the Reach property.
