My estimation placed the number of Keldrinite at 6-10 among active players. The quest has been updated to allow for KLS and Karmor to substitute as Keldrinite, however the amount of Keldrinite needed will increase as a result.
So if only pure Keldrinite is donated, the original amount will be used. If KLS or Karmor is donated, the amount needed will be adjusted. This is not scripted and I will handle it manually.
