Bruce allowed his blade of ki to dissipate, refocusing it into the chains he'd used earlier, wrapped several times around his body. Rather than reform the earth material that crumbled as a result of Prisma's electricity, he leapt off into the air from it, using the chain to wrap around the leg that wasn't crackling with energy to swing himself through the giant's thighs and around one side. The chains only shot out from around his body, leaving his hands free again. 
Using one, he gathered the massive amount of material that had formed the network of platforms behind him, sending it up directly over Prisma's head and body into a huge mass of earth and rock.
With the other hand, Bruce hardened the mud around Prisma's ankles until it had the consistency and density of cement, hoping to prevent the giant from moving to avoid the combination assault he was planning. Meanwhile, he continued shooting out lengths of chain, anticipating the need to swing from another part of the giant's body.
