  We introduce a high uniformity generalization of the so-called (projective)
norm graphs of Alon, Koll\'ar, R\'onyai, and Szab\'o, and use it to show that
$$\operatorname{ex}_{d}(n,K_{s_{1},\ldots,s_{d}}^{(d)}) = \Theta\left(n^{d -
\frac{1}{s_{1}\ldots s_{d-1}}}\right)$$ holds for all integers
$s_{1},\ldots,s_{d} \geq 2$ such that $s_{d} \geq \left((d-1)(s_{1}\ldots
s_{d-1}-1)\right)!+1$. This improves upon a recent result of Ma, Yuan and
Zhang, and thus settles (many) new cases of a conjecture of Mubayi.
