Quenching Acid Notes & Tips

  • Note that on NG+, Previously Acquired Weapon Upgrades are converted into Quenching Acid. This gives you an additional 8 Quenching Acids. Defeating the 3 Hadern Weapon Boss Fight in NG+ also gives you 3 more Quenching Acids. Adding the 8 New Buyable ones added to the Inventory of Sister Genessa and you get 19 More per playtrough on NG+.
  • If a player acquires the 11 Quenching Acids in their first playtrough, then acquires the (11+19 = 30) ones on NG+, they should have 41 Quenching Acids, enough to upgrade all four weapons to their +10 Max By the end of NG+.
