Ah, no. This was changed back a few months when we did all those sweeping changes.
It should be 1d6/caster level up to level 10 plus 1d6 per ever two caster levels past 10.
So a 12th level caster gets 11d6, a 20th level caster gets 15d6, etc.
Looks like this one was missed in our documentation sweep.
