The wisp elixir is an item used in the Wisps of the Grove Distractions and Diversion. It is given to the player after correctly handing in different coloured wisps to Teelee. It is then poured into the offering cradle at the centre of the Lost Grove in order to gain the experience reward in Farming and Hunter equivalent to the experience gained from a medium XP lamp.

The wisp elixir has a drink option, but the player will not drink it due to the fears of growing a tail or turning into a fairy.
