From the FAQ:
If Plaguebearers are killed during a beginning of battle
effect (such as Khorne’s Blood Frenzy card), then for
each Plaguebearer killed during the beginning of battle
step, the Nurgle player assigns one hit to that opponent’s
figures before proceeding to the standard battle.....
Can the damage caused by the Plaguebearers in the early hits phase be stored for the main battle phase? (like the hits caused by Blood Frenzy)?
