Attacking an Elder?
The Tremor Cane was a very well designed weapon. It had a powerful shock absorbing system which allowed the wielder to completely avoid experiencing the "tremors" of the cane.
But only up to a point.
Against most objects that human beings could wield with their bare hands such as shields and swords, the Tremor Cane would definitely blast through them like hot steel through butter.
Or a more apt illustration would be a hammer being smashed on a lump of butter.
That was why it was a Grade B weapon - Extremely Dangerous at Close Distance.
However, against stronger objects such as the armor of a heavy mecha or even a well made tank, the Tremor Cane was completely useless.
In fact, it was more than useless. Wielding a Tremor Cane as smashing it against armor above its ability to destroy would force the cane's destructive vibrations to travel up the wielder's hand instead of through to its target.
It would be as though the wielder was using the Tremor Cane on his own hand.
