Safe and Easy Farming Radial Cursed Nourishing Abyssal Gem from FRC Rom for Holy Moonlight Sword

Glyph: v5v5fpsd The best you can get from it is +19.5% ATK, +15 Physical secondary. I know, I know that +19.3% ATK up from Gargoyles are almost as good as the Radial Abyssal Nourishing from Rom, but I just can't say no to the sweet Abyssal gem. Here I used the Whirligig Saw, but as long as you're using a properly gemmed weapon (like 27.2% gems from watcher, which are easy to farm), you can destroy this giant spider.
