Without boost again

After clearing normal runs, I surprisingly got an S-rank 'Dragonkin's Flame-Knot Spear' ✨️ ...Seriously, isn't it too rare to drop from normal runs!? This is equipment dropped by an AA-rank monster, you know!? Σ(･ω･ﾉ)ﾉ And actually, I had already gotten an S-rank 'Flowing Stone's Flame-Knot Spear' before... why is it only this one when other high-rank equipment hardly drops? (lol) It took me about 2 years to get an S-rank drop of the Ice Dragon Scale Shield I posted last time... lol Well, I guess the Flame-Knot Spear is probably the strongest spear right now, so I'm grateful lol Now I have a wish I almost never have... Please give me one more S-rank Flame-Knot Spear 🙏 Then I can craft my first SS-rank weapon from an AA monster ✨️ I hope it drops casually at some point 🙏
