An Entrati-faction Incarnon weapon. Initially, this was a difficult task for me because I couldn't figure out a "lab equipment" angle for "what would you use something on your fist for in a lab?" and then I realized I just wanted to punch stuff with coins instead. The obols are meant to enhance the punching experience by sproinging out just before impact.
Credit to Nikita Leshakov for the Incarnon form idea, in which we decided to take an alternate approach vs. the Zariman Incarnons and suggest that these are "lab experiments gone rogue". The tendrils burst out of the body of the weapon through the eyes of the obols, like monstrous, uncontrolled, beastly fingers.
