Let me show you what I learn : Each time you deal damage to more than one target, you can allocate all damage to one target you want

IMPART YOUR WISDOM, ALEPHAN : The first time at your turn you deal non-combat damage, deal it another time, you can choose new targets

{x}{r}{r}{u}{u} : This is, the answer : Deal X damage to all enemy creature and all players
