you're right I shouldn't have called it that. I have no other useable 4 star claymore, so I just used spine and didn't think about it enough. I'm pretty sure you can get similar results as completely f2p if you use the Ultimate Overlord's Mega Magic Sword
You are right, I don't have any of the f2p options so I used spine. I do think that spine is very comparable to Tidal Shadow (carftable), Ultimate Overlord's Mega Magic Sword (event weapon), or Blackcliff Slasher (starglitter weapon). Those options are almost the same, I just used what I had (• ▽ •;)
