After that, they also created three large Frozen Cylinders that would serve as their trump cards. They each held 100 milliliters of his frozen blood. So, if they faced a behemoth of a creature, the large Frozen Cylinders would prove effective.
Of course, that wasn't the only grenades they possessed. The Seamstress also accumulated her Heat Radiance in some coral cylinders she made. They worked similar to the Frozen Cylinder. But, there was a difference here.
The Frozen Cylinder directly used his frozen blood to create a freezing effect. But, the Seamstress didn't possess such blood. So, she used another technique to make bombs out of it. As she already stored intense heat within her coral sword and only unleashed it when necessary to melt objects, she used the same principle here.
