Double Hit exclusive or more common in Ancient City loottable

A “double hit" can also be called as an “echo” of the previous hit (ancient city sound and vibration theming), and double hit is quite powerful allowing you to do double the max damage you can do in one hit (albeit there only being a chance of so). Having it be exclusive or more common in the City would enrich it from both a theme perspective, and from a balancing perspective, so you go through a challenge to get the enchantment and not from the comfort of spawn’s enchanting table
