Warlocks are an extremely valuable class in World of Warcraft. While they’re definitely worth bringing to certain dungeons and raids for their damage numbers, the element of convenience is also extremely present in the class as Warlocks have one of the most commonly needed spells: Portal of Summoning.
Portal of Summoning will bring players in your party to a given location provided you have the assistance of two other party members to complete the ritual. The spell should be extremely familiar to any World of Warcraft player who has run a dungeon or raid before as Warlock summons are one of the most highly demanded spells of convenience in the game’s history.
In WoW Classic’s Season of Discovery phase two, Portal of Summoning can be learned via a skill book: the Grimoire of Portal of Summoning. Acquiring this book will allow you to permanently add Portal of Summoning to your WoW SoD character’s spell lineup. Here’s where to find the skill book for Portal of Summoning in WoW Season of Discovery.
Warlock Summoning Portal skill book drop source and location in WoW SoD
Like most skill books in WoW SoD phase two, the Grimoire of Portal of Summoning can drop off certain dungeon bosses, especially bosses found in the Scarlet Monastery. WoW database Wowhead lists several bosses as being the most reliable drop sources for the Portal of Summoning skill book, with Scarlet Monastery being a frequent contributor. These bosses include Bloodmage Thalnos and Interrogator Vishas from the first wing of Scarlet Monastery, the Graveyard, as well as Houndmaster Loksey and Arcanist Doan, bosses from the second wing of the dungeon, the Library.
Scarlet Monastery is a dungeon that you should be running frequently in phase two thanks to the abundance of gear that can be found there. If you want to get a skill book for your class early on in the leveling process, though—such as Warlocks’ Portal of Summoning—you should head there as soon as you’re eligible and get to farming.
