This battle wasn't easy for Rhode.
If the phantom possessed Lize's actual strength, Rhode would've gotten rid of her in a split second. Although he wasn't sure what the Mind Devil had done, it had magnified Lize's mental strength and in her mental world, she possessed powerful competence and strength. It was due to this reason that Rhode and Anne didn't have an easy time against her.
From their previous encounter, Rhode realized that the phantom was a BOSS between level 60 to 65. Fortunately, the phantom didn't have Lize's strength and its speed, strength, and reaction was similar to the BOSS. Apart from that, she couldn't use any special skills nor the usual spells which Lize used.
However, the fight was still tough.
Because Lize understood Anne and him too well.
