Active Abilities Are Insane!
Krune and the Seamstress spent a couple of months understanding their active abilities.
Even an active ability was still limited by their mortal bodies. If they expend all their stamina, they would be able to condense the Supreme Monster forming their active ability. Plus, the size of the monster created dictated the strength the Supreme Monster wielded.
When summoned, just like the Checkpoint Turtle summoned by Gehen, they were able to compress air in their bodies to launch an attack.
The Seamstress's active ability was called Great Dipper, which came from one of the adults. It was capable of high-speed flight between multiple points. It was a great advantage in the presence of numerous enemies.
Its special ability was inhaling and compressing air before shooting them out of the stinger-like bullets. And, each air bullet packed a lot of punch, enough to make a hole 10 centimeters deep into the rock pillar.
