do you need a full prefix/suffix waystone,
or could i just have 3-4prefix and have it turn into 16?
you do not need full prefix / suffix
79: regular node on map with nothing
80: irradiated or corrupted / cleansed (must look for the +1 to monster level area)
81: irradiated + corrupted/cleanse (must have the +1 to monster level area)
82: irradiated + corrupted/cleansed + t16 waystone (from vaaling)
hopefully that helps. happy farming!
