The demonologist is the mightiest of sorcerers, wielding the power of hell and earth and capable of conjuring pillars of flame or titanic storms of electricity.
So great is their occult knowledge they can bargain a servant of hell into doing their bidding, a guardian daemon of warped beauty and terrible might.
Demonologists concentrate solely on sorcery and the potency of their spells is unmatched, as capable of eliminating a single enemy in a hellish inferno as destroying enemy lines with forks of lightning. They can sacrifice their own life-force in return for more occult power and they are most potent when they can devote their spell energies solely to attack.
[edit] Game Description
Demonologists are magic experts who have aligned themselves strongly with otherworldly demonic forces. Their damaging magical attacks drain from the caster's own life force. The class also wield augmentative magics and summon demonic servants to do their bidding.
[edit] PvE
In the facts, demonologists are a dps class. They excel at dealing high damage in short period of time. They might not be the ones that deal the highest amount of damage, but they are very good at dealing their damage to groups of enemies. Inferno of Amher and Shockblast both have a very large area of effect. Most spells used eventually deal at least a certain amount of area damage.
Demonologists will also deal damage over time, burning enemies, for example, even though they're not as good at it as other classes (necromancer comes to mind in particular).
When well played, towards the end of the game, demonologists can also act as a pretty efficient off-tank, being able to keep an enemy off the group for a long time. Use of Storm Chains will root an enemy in place for up to 17 seconds at rank 5, Gate of Hell will root it in place long enough for Storm Chains to reload, Detonation will knock down even full-plated opponent and their neighbors, and Fiery Torment will stun the target for up to 5.5 seconds.
Demonologists will also have a couple abilities useful for the whole group. Their pet, first, will increase life, stamina and mana regeneration, max life, max mana, or damages, depending on the needs. The feat Unholy Hate grants a spell that will boost damage of the whole team by 10% for 8 seconds.
The weakness of the demonologists, however, is the facility with which they die. Their best strategy to survive is "kill before you get killed". Use of their crowd control abilities is also highly recommended. Demonologists have a couple last resort spells, such as Planar Shift that only comes at level 75, but greatly increases immunities and evasion rate for a mere 6 seconds.
[edit] PvP
In PvP, a demonologist might not fare too well at low level, before they get all their crowd control abilities. After that, between their range, their high-damage and their (low) damage over time, they can get pretty decent, especially against melee classes. Here again, the strategy will be "kill before I get killed", and for that, Pact with Set can help a whole lot.
