  In the context of Type IIB LARGE volume orientifold setup equipped with
poly-instanton corrections, the standard single-field poly-instanton inflation
driven by a 'Wilson' divisor volume modulus is generalized by the inclusion of
respective axion modulus. This two-field dynamics results in a "Roulette" type
inflation with the presence of several inflationary trajectories which could
produce 50 (or more) e-foldings. The evolution of various trajectories along
with physical observables are studied. The possibility of generating primordial
non-Gaussianities in the slow-roll as well as in the beyond slow-roll region is
investigated. We find that although the non- linearity parameters are quite
small during the slow-roll regime, the same are significantly enhanced in the
beyond slow-roll regime investigated up to the end of inflation.
