Duty Eternal

Use this Stratagem when a BLOOD ANGELS DREADNOUGHT model from your army is
chosen as the target for an attack. Until the end
of the phase, when resolving an attack made
against that model, you can reduce any damage suffered by 1, to a minimum of 1 (this is not cumulative with any other rules that reduce the
damage).
Having tasted death before, the Dreadnought pilot is determined to do his duty before his end finally comes.
