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