FATED MUTATION

Use this Stratagem in the Fight phase, when a THOUSAND SONS CHAOS SPAWN unit
from your army is selected to fight. Until the
end of the phase, instead of rolling for that
unit’s Mutated Beyond Reason ability, you can
select the result. Until the end
of the phase, each time you determine the
number of Attacks a model in that unit can
make, add 1 to the result.
