The floods are busy being absorbed by NA terraformers. NA are not because the metal is busy being held at bay with hau and other shields.
Fragmentation is channeled to shatter the Hau shields.
Other bits of metal try teleporting inside NA armor and then absorbing it.
A crushed Destral Ironclad falls from the sky.
The bits of metal have a fun time slamming into NA teleport blockers. As fun as sprinting into a brick wall. Fragmentation is dealt with using Repellers, sending the blasts right back into the offending rahkshi.
The Ironclad is intercepted with pulse bolts as sunbeam drones and NAtoran scramble to get matoran out from under where it's falling to.
