Is there a safe-spot to defeat the warlord in the tree gnome village quest on runescape?

Talk to the Warlord and kill him to retrieve the other two orbs. If you are a low level, it is possible for you to poison the warlord and then hide behind a tree and wait. If you can just kill him, it is recommended because he has over 100 HP.

Otherwise, there is a safe spot (the Warlord can only stay inside a large box, so you can use magic or ranged to kill him without getting hit by him) to take advantage of, so bring food, incase he gets a lucky hit on you every now and then.
