Sadist Blade

The Sadist Blade is an enchanted sword that becomes more deadly the more it is used. It starts out dull to the point of bluntness, though while it does not inflict particularly wounding blows in this state, it causes exceptional pain in those it strikes. The more pain its user causes, the sharper and more powerful the blade becomes. Additionally, the pain that it causes can devastate and disable foes who are unable to endure it.
=== Sadomasochism ===
If the Sadist Blade is dual wielded with a Masochist Blade, it will benefit from the pain caused by it as well, including the pain it causes to the user itself.
== Variants ==
There exist variants for piercing and blunt Sadist weapons as well. Notably, the blunt one starts off soft and grows harder and the piercing one starts of blunt and then grows a bulge or multiple bulges that protrude spikes. One such piercing variant is a disgusting and fleshy bat that hardens, grows warts, and finally claws as it activates its power.
