The amount of Aether that Andar was summoning would have drained a Rank 4 Mage dry, but the battle was just beginning. Without access to spells, to achieve anything he had to be pushing out ridiculous amounts of Aether.
This was reflected in their surroundings, as the chasm created from their clash expanded as the energy inside here could not be contained by the space. The area of expansion reached more than a thousand feet wide before it slowed, this was because they were inside the Black Tower, anywhere else and half a continent would have been flattened.
Below Andar the mouths of the ten massive Venus Fly Traps opened and they cried out, vomiting out large oily clumps of darkness that began to fill this space, restricting vision and sticking to the Wind blades reducing their speed and sharpness.
