What exactly do they do? As far as I can find, they autocast spells with x10% more damage and 5-25 mage attack bonus? I came across the wand in some NMZ guide I was looking at, and he didn't have any runes in his inventory, how does he autocast spells without runes? Are wands really worth it?
SOTD is worth it, all others are pretty meh. Trident is good if you like PVM (Zulrah, Kraken, Barrows, etc...) though
I think master wand is the best 1h that can autocast ancients (not sure). As for not having runes, maybe he had a rune pouch
