Klaus gave no time to waste, as she knew the anatomy of trolls well enough. No matter how durable they are, the heart, if stabbed, will let them lose consciousness. Just like the training this morning, Sir Fleuri has carved up another opportunity for her. And she wouldn't let it go away, not this time.
Klaus, with her one hand grip on the edge of the handle, thrusted her left hand towards the troll, making a slight twist as the tip sinks into the troll's heart. Her 'Piercing Moon' style was that same familiar technique that is used on various occasions, and she only uses that when she was certain she could kill her enemy.
Withdrawing her blade from the foul coloured corpse, Klaus sliced the body into pieces to lighten the falling weight of the troll's body. After all, an attack must have a beginning and an end. Despite thinking that way, she didn't bother shaking the blood off the blade. With her blade's fuller still thick with troll's blood, she galloped her horse towards another troll. She splashed the blood at the troll's eyes by making one rough swing of her sword, pulling the rein just ahead of the blinded troll's reach to observe what that thing would do next.
