In case you haven't figured this out yet d66 is meant to be 1d6 for the 10s and 1d6 for the 1s... the lowest being 11, highest 66. 6d6 would make the highest 36.
I didn't actually know that. Nowhere does it explicitly state how to read such a table. I've also never encountered such tables before so didn't understand how to read them. Thanks for the clarification though!
