  The early universe could feature multiple reheating events, leading to jumps
in the visible sector entropy density that dilute both particle asymmetries and
the number density of frozen-out states. In fact, late time entropy jumps are
usually required in models of Affleck-Dine baryogenesis, which typically
produces an initial particle-antiparticle asymmetry that is much too large. An
important consequence of late time dilution, is that a smaller dark matter
annihilation cross section is needed to obtain the observed dark matter relic
density. For cosmologies with high scale baryogenesis, followed by
radiation-dominated dark matter freeze-out, we show that the perturbative
unitarity mass bound on thermal relic dark matter is relaxed to $10^{10}$ GeV.
We proceed to study superheavy asymmetric dark matter models, made possible by
a sizable entropy injection after dark matter freeze-out, and identify how the
Affleck-Dine mechanism would generate the baryon and dark asymmetries.
