TCoE Typo?

Noticed while reading the Subclass for Barbarian Wild Magic, it mentions a d3 dice roll twice for a 6th level feat. Is this a typo? I feel like it should say d4 instead.

No, d3 is correct.

Obviously a three-sided polyhedron is impossible, so a d3 is just a d6 with the final result halved (round up).

There is a typo in my copy though, page 19 spells material as materiel. EDIT: Nevermind, in military context it is in fact materiel.

No it isn’t, I have a bag full of them. They just don’t use them in the dice set for D&D.
