Dilatonic black hole dyon-like solutions in the gravitational 4d model with a scalar field, two 2-forms, two dilatonic coupling constants λ i 0, i = 1, 2, obeying λ 1 −λ 2 and sign parameter ε = ±1 for scalar field kinetic term are considered. Here ε = −1 corresponds to ghost scalar field. These solutions are defined up to solutions of two master equations for two moduli functions, when λ 2 i 1/2 for ε = −1. A set of bounds on gravitational mass and scalar charge are presented by using a
