The skill [mana disruption] could only cover so much range and based on the user, the range could become even smaller. If you can just get out of its range, you can easily avoid the skill.
On other hand, if the mage who is being targeted with [Mana Disruption] skill is too powerful and has achieved a profound understanding of the mystical energy, they would easily be able to shake off the effect of the skill.
Whereas, the [Essence Mana Disruption] was a Rare skill of legendary tier that not just disrupts the mana, but interferes with the very mystical particles that make up the mana itself. It is a skill much more powerful and annoying to avoid than the former.
Bea looked at Karina after activating that skill of hers and was inwardly shocked a little. For a mage it was a taboo for their magic to be disrupted midway since doing so would not only disperse their magic but they themselves would receive a fierce backlash tantamount to suffering a severe blow.
