Another Lunar Isle example is if you're going after Jad in the Fight Cave. Many people like to Vengeance Jad, which requires the Lunar Spellbook. It's always been annoying to switch before, but now you can teleport straight there, change spellbooks, and be on your way to Jad without any wasted time.

But wait... there's more! I'm sure you've heard those pitches before. In this case, you also get free runes, and free essence every day. I haven't tried this yet, but here's what I understand: You get 100 elemental runes every day, or you can pick any other rune and get 5. If you apply an elemental talisman to the Wicked Hood, you'll get to do this twice a day. You also get 100 unnoted essence every day... and that's upgraded to 100 Pure Essence if you used an Omni-Talisman.
The Wicked Hood takes the place of any runecrafting tiara, and of any talisman. I've already sold off all my talismans except the ones I use for Summoning. Keeps on death (you don't lose it), and if you somehow lose or destroy it, the Wicked Hood can be replaced by Tam McGrubor. For Free. And it will still know all the locations you've taught it.
