Decided to treat myself to some new, decidedly non-shiny, and arguably weaponizable math rocks...

also got some shiny metal dice for the local group as Christmas gifts...

(the eleven-packs were bought straight out, most of the gold dice were free via the holiday sale, and the oversize metal d20s were freebies... they could do some serious damage in a pinch)

oh yeah, those metal ones are dangerous

I have a set of metal ones with a d4 that would actually send someone to the ER if you stepped on them

the oversize d20s are 2oz each, and about 1" across

so yeah... with a good windup, they'd do proper bludgeoning damage.
