When Dante and his group spotted the cave opening far in the northern area of the Alanigan Mountains, they kept advancing toward it on air for a few more minutes before descending to the ground.
Dante and Asphodel were able to completely hide their presence by suppressing their aura. However, the vampire sentinel and the rest of the Omega Team couldn't do it, as it wasn't a skill they could quickly learn since it required years of training.
The main reason the pair decided to hide their aura was to prevent their enemies from sensing them before reaching the cave base.
While ordinary humans weren't able to detect it, a Death Knight wouldn't have a problem with it.
Still, Megan commented that if the guards in the base were androids, then hiding their aura wouldn't make a difference since the androids used a scanner to detect a person's body heat.
