  Let $G$ be a complex adjoint reductive group and $R$ be the group ring of the
coweight lattice. We construct the universal monodromic big tilting sheaf on
base affine space and show that its endomorphisms are $R \otimes_{R^W} R$. Our
arguments are self contained, so formal completion implies a short new proof of
Soergel's prounipotent endomorphismensatz with arbitrary field coefficients. We
give a Soergel bimodules description of the universal monodromic Hecke category
and deduce a conjecture of Eberhardt that uncompletes Koszul duality.
