Now that you have all three keys, head back to the Varrock Castle. Talk to Sir Prysin again and you’ll hand him the three keys. He’ll then give you the Rose Zuly sword Silver light.

Equip the sword along with some armor and prepare to fight Delrith. Delrith is in the middle of the Stone Henge south of Varrock. Attack him.

After a couple of hits, you will recall “What were the three incantations again?” Then a list of options will appear on the top-left corner of the screen. Click on the bottom one which should say “Carlem Aber Camerinthum Purchai Gabindo.” You will say the words and Delrith will regain his heal back.
