Demonology is all about fighting alongside an insanely powerful Demon and getting as much value out of it as humanly possible. Your Demon contributes a MASSIVE amount of your overall damage and the Demonology tree also gives you a TON of powerful buffs for keeping it alive and hitting the boss. You still use the normal
Warlock toolkit with DoTs, spells and Curses, but much more of your damage and survivability is tied to your Demon and the talents revolving around it.
WoW Forever pushes this playstyle MUCH further than Classic.
Unholy Power gives your Demon a big damage increase, while
Fel Vitality improves both its resources and your own Mana pool.
Demonic Energies is an underrated talent that helps keep your Demon alive through you dealing spell damage and also restores its Mana whenever you use
Life Tap. Deeper talents like
Demonic Knowledge increase the spell damage of both you and your Demon and of course the infamous
Soul Link gives you some of the best survivability in the game.
Demonology can be played with both Shadow and Fire builds. Shadow builds lean more heavily into
Shadow Bolt fillers and uses
Summon Succubus /
Summon Incubus, while Fire builds make much better use of spells like
Searing Pain fillers and uses
Summon Imp. This gives Demonology two powerful builds to choose from depending on the gear you have and which playstyle you prefer.
One of the most fun talents is
Demonic Pact. This lets
Demonic Sacrifice one demon and have another one out, as long as it's a different one than the sacrificed one. Combined with talents like
Master Demonologist, this opens up some extremely strong interactions where both you and your Demon are getting buffed at the same time.
