Sam didn't waste the chance.
He disappeared once again and reappeared beside another shadow undead that was closest to Marron.
*BANG*
Marron braced herself for the impact and blocked his move.
*BANG*
She was able to block him easily, but not the undead that came from behind her. The undead hacked on her back, expanding the previous injury that was already bleeding.
Marron winced at the sudden pain and kicked backwards, the undead was destroyed in a puff of smoke. Sam also did the same and disappeared from there, reappearing near an undead that is far away.
By now, Marron dealt with two of Sam's undead, but the problem is they are just shadow undead, they could be respawned as long as Sam had enough spiritual energy and a decent control over it. Sam did have both of them.
