Lunar Diplomacy Guide
Before I start, I'd like to give a shout out to Lightz On, he made the original quest guide but it has since become outdated.
Requirements:
Level 40+ in the combat skill of your choosing (I recommend Range or Melee)
43 Prayer - Please just get 43 prayer before you start this...
A hurty thing you can use to hurt things (Melee weapon | bow/xbow, arrows/bolts)
Maybe some food
Some prayer pots
The Quest:
Tip: Turn on protect from melee before she teleports you.
Start the quest by talking to Oneiromancer ("floating chick by the yew trees south of edgeville aka ;;home" - Lightz On)
Tip: Turn on protect from melee before she teleports you into the arena.
Once you have skipped all of her dialogue you will want to tell her that you are ready to fight (TURN ON PROTECT FROM MELEE BEFORE YOU CLICK YES) She will then teleport you into the arena.
Once you are in the arena, kill the spooky things that want to hurt you, there are 4 of them.
Once they're all dead you have officially completed the quest! You can now use the Lunar spellbook and buy stuff from her shop.
Here is a picture of her shop:
I am proud of you and so is the Oneiromancer.
