Blamish oil

Blamish oil is a quest item used in Heroes Quest. It is made through Herblore skill and turns a normal fishing rod into an oily fishing rod. Oily fishing rods can only be used at lava fishing spots to catch lava eels.

To make Blamish oil, use Blamish snail slime and a Harralander potion(unf) (using a clean harralander on a vial of water). It needs level 22 Herblore to be made and gives 80 Herblore experience.

It is also a rare drop from the citizens of Canifis, that is when you defeat them entirely with the wolfbane dagger so they dont transform into a Werewolf.

Blamish oil has "Drink" option, but when you choose drink, your character says, "You know... I'd really rather not."
