I have been trying to get the Ice Elemental Residue for Frostfang III collection and it says you use the jar on the remains of the Ice Elemental the Shaman summons for Frozen Maw but I have fought it 4 times and got nothing. I clicked my Glacial Imbued Jar before the event and killed the boss within time, used it on the Shaman’s body, ran around the spot the big Ice Elemental floated over and kept double clicking but got nothing. It is either a but or I need to do something extremely specific that the wiki doesn’t mention. Please help.
