Items from the tool belt are not listed unless they do not work or are not automatically added.
Silver sickle (Can be made from a Silver bar and a Sickle mould or bought from the Grand Exchange. Not able to make unless part of the Nature Spirit quest has been completed. Talk to Filliman to obtain the ability to craft this.)
Talk to Drezel, who is located underground near Paterdomus - The entrance is north from the temple's door. You must have six empty inventory spots; Drezel won't discuss the quest with you if you don't. (2•✓•4•1)…
Is there anything else interesting to do around here?
Yes, I'll go and look for him.
Yes, I'm sure.
Exit into Morytania and travel south to a fence.
Look along the fence for a gate and go through it. You must go through the gate or Fililman won't appear at his grotto.
Go South until a round island is found with a grotto tree.
Jump across the broken bridge and onto the island.
