7. Blackrazor

Closing out the trio of sentient weapons that can be found in the heart of Keraptis’ mountain lair, we find Blackrazor. Unlike its kin, Wave and Whelm, Blackrazor does not seek to protect anyone or anything. Blackrazor wishes to consume the world, plunging all into the void.

Blackrazor is a greatsword, and its entire form seems to shimmer like the night sky. When a living creature is killed by Blackrazor, its soul is absorbed into the weapon. When this happens, you gain a substantial buffer: temporary hit points equal to that enemy’s hit point maximum. Just think about how many hit points you would have after slaying a dragon! 

While those hit points last (up to 24 hours), you have advantage on all attack rolls, saving throws, and ability checks, as Blackrazor uses the soul’s energy to empower you. Blackrazor can also sense every soul within your vicinity, and grants you this knowledge. 

It also has the power to grant you unnatural speed for a duration, though it decides when it wants to do this. Blackrazor has one restriction: it will not allow you to harm undead. In fact, it will kill you if you try. Overall, one thing is clear, you don’t want to be on the wrong end of Blackrazor.
