Crystal Shapeshifter

Crystal shapeshifters are Slayer monsters located on Tarddiad after completion of the quest The Light Within. They can fight with all three combat styles, and similar to the Revenants they will switch dependant on the combat style you are using. Crystal Shapeshifters are more dangerous than their combat level suggests and shouldn't be taken lightly if fought for the first time. They inherit several combat abilities such as stuns and damage-over-time abilities, as well as two unique abilities.

Crystal shapeshifters switch their combat styles dependant on both the weapon you are using, and any protective prayer you are using, prioritising your protection prayers. For example, if a player uses Magic weapons, it will switch to Ranged, but if the player has Protect/Deflect Missles prayer in use, the Crystaline shapeshifter will switch to Magic or Melee.

Crystal shapeshifters have two unique abilities:
 * They can remove / interrupt any damage-over-time, stun and bind debuffs applied to them. Combo attacks however will not be interrupted, unless the player is stunned.
 * Occasionally they can turn into a crystal spiked ball and lunge at the player for extreme Melee damage, spiking up into nearly 6.000 Lifepoints.
