The Rahski reacted with a bolt of chain lightning, but Nokama wasn't sitting and waiting for it.  Instead of springing, she rolled to her left.  The bolt struck where she had been, hitting the stream of protodermis and traveling along it right back to the black-white Rahkshi.  The current slammed into the creature and sent him flying.

Nokama swung her hydro blades hard and cleaved open the wall at the site of the leak.  Liquid protodermis gushed through the gap, rapidly filling the cave.  Both Rahkshi's faceplates opened to reveal very disturbed kraata, screeching their rage.

Then she noticed an unexpected benefit of the flood.  The liquid was disturbed a few feet to the right of the tan-blue Rahkhi.  That was where the true creature stood, well away from the illusion.  She mustered her energy and sent a mini tidal wave toward the spot.  When it struck, the illusion vanished and the real Rahkshi appeared, knocked off its feet.

"One out of the fight, one stunned," she said to herself.  "And one to go."

She had half hoped the silver Rahkshi would back off.  But if anything, all she had succeeded in doing was making it angry.  Wary, too - having seen what happened to its brother, it wasn't going to be hurling any more lightning bolts around.  Still it advanced toward Nokama though the wait deep liquid, claws outstretched.

The Toa of Water nodded.  She knew the best she could hope for was to slow down these creatures and buy time for escape.  So far, she had been lucky.  But now the silver Rahkshi had taken her measure and was prepared for her moves.  All but one, she reminded herself.

Without warning, she dove beneath the surface of the protodermis and rocketed toward the Rahkshi.  At the last moment, she veered off and began circling it at enormous speed.  By the time the creature grasped what was happening it was too late.  The Rahkshi was caught inside a powerful waterspout, heading for the ceiling.

Nokama kept swimming, faster and faster until she heard the sharp crack of Rahkshi armor striking the stone high above.  Then she abruptly stopped and let the spout dissipate.  The Rahkshi crashed into the liquid and then floated to the surface, lying on its back.  Its faceplate was open and the leechlike kraata inside was trying to squirm out.
