I don’t see why there’s any reason to choose the current boost in raw damage when the other gems give just as much of a damage increase, plus they freeze/burn/plague/shock the enemy. So to make the gem slot more worth it, I’d say something like a +5 to poise damage would be more interesting. I could see some weapons benefiting more from a poise break than just going ice or such for the eventual freeze.
But that’s just my thoughts. Is anyone currently using the Chipped Spike? If so, why?
