/u/mark_ggg was it a typo or something?
We changed the description because the old one was incorrect on several points about mechanical interactions. Apparently in doing so a number went from being explicitly stated to not being so.
For the record, the default amount of base damage attacks deal is 100%, not 0%, so if the gem actually lost that stat, that would be a huge buff, not a nerf. But it hasn't lost the stat.
