Light Form is a Seren prayer. It doubles the chance of Seren-aligned spell effects occurring when using abilities. The spells affected by this boost are the Opal, Sapphire, Emerald, and Ruby Auroras. It requires 80 Prayer and like all other Seren prayers and spells it requires completion of The Light Within. It is the opposite of Dark Form.
In addition to its listed effect, it also increases the effectiveness of the skilling spells. Using Light Form with Crystallise gives 87.5% more experience instead of the usual 50% when Woodcutting, Fishing, or Hunting, and gives 40% more experience instead of 20% when Mining. Using it with Crystal Mask decreases the fail rate of pick-pocketing even further.
With the Grace of the elves equipped, Light Form's prayer drain is halved to 150 points per minute.
