We calculate a resummed equation of state with lattice QCD simulations at imaginary chemical potentials. This work presents a generalization of the scheme introduced in 2102.06660 to the case of non-zero , focusing on the line of strangeness neutrality. We present results up to on the strangeness neutral line in the temperature range . We also extrapolate the finite baryon density equation of state to small non-zero values of the strangeness-to-baryon ratio . We perform a continuum extrapolation using lattice simulations of the 4stout-improved staggered action with 8, 10, 12 and 16 timeslices.
