  We formulate a family of equations of state for Quantum Chromodynamics that
exhibit critical features and obey the charge conservation conditions present
in heavy-ion collisions (HICs). This construction utilizes the first-principle
Lattice QCD (LQCD) results up to $\mathcal{O}(\mu_B^4)$ by matching the Taylor
coefficients at each order. The criticality of the equation of state (EoS) is
implemented based on the well-established principle of universal scaling
behavior, where QCD belongs to the 3D Ising Model universality class. The
critical point can be placed in a range of temperature and baryonic chemical
potential relevant for the Beam Energy Scan II at RHIC. Furthermore, the
strength of the critical features can be varied as well. This flexibility is
embedded in four free parameters, that could potentially be constrained by the
experimental data. We will discuss the features and versatility of our EoS, as
well as present the relevant thermodynamic quantities which are important for
hydrodynamical simulations of HICs.
