Among the first skills you will gain as a seer is the trance. Seers have the ability to go into a trance state, during which special benefits are conferred. Three unique trances are available in Immortal Throne: the trance of empathy, which forces enemies to share in the pain that they inflict upon you; the trance of convalescence, which allows you to heal at a remarkable rate and absorb damage in the heat of battle; and the trance of wrath, which weakens and burns all enemies around the player with dark psionic energy. Trances are extremely powerful, but only one can be active at a time, so the player will learn which trance is best for each situation and use it accordingly.
In addition to trances, the seer may call upon the sands of sleep, sending foes into a deep slumber that removes them from combat, allowing the player to either flee or smite them down at his leisure. Another exciting early skill is psionic touch, which grants the seer the ability to attack multiple enemies at once, regardless of his chosen weapon, and also increases all damage dealt, either physical or elemental.
Skills like distortion wave let the seer attack large numbers of monsters at once before charging in to destroy them by initially harming them or "debuffing" them--that is, de-powering them by removing any protective magic they might have and reducing their strength and skills. And what better way to charge in than with phantom strike, a new dream mastery skill that grants the ability to slip into the dream world and become invisible, only to resurface and strike a chosen foe with devastating force? With the dream stealer modifier, this skill will let the seer strike an entire group of enemies and siphon energy from them as they die.
Once in the heart of a monster camp, a seer can use the distort reality skill to send forth a ripple of reality-bending mental energy that does tremendous physical and vitality damage to all foes. With the temporal rift modifier, the skill does even greater damage, and can halt the flow of time for all enemies in the area.
Finally, the dream mastery makes a new pet available to you: the nightmare, a creature born from the darkest dreams of men. The nightmare can burn enemies with beams of psionic energy from its hideous eye, and confuse entire crowds of monsters with its hypnotic gaze. Its greatest power, though, is called mastermind. With mastermind, the nightmare can buff itself, as well as all other pets under your control, turning your small band of creatures into a veritable army.
With these and other unique new skills, the dream mastery stands strong on its own. However, it also serves as an excellent complement to any of the existing eight masteries in Titan Quest. It has been designed to be the ultimate hybrid class, equally good with either a melee warrior or a spellcaster. If you're a fan of pets, the nightmare pet and its mastermind ability will make you much, much more effective. If you like to wade into melee combat, skills like psionic touch will make you much more deadly, and skills like distortion wave will allow you to weaken a camp of monsters before you take them out. As a pure caster, the trance of empathy will provide you much-needed protection from ranged attackers like archers by returning their damage back to them. No matter what your character build, skills like sands of sleep and distort reality are enormously valuable for crowd control.
Another great thing about the dream mastery is how well it is suited to cooperative multiplayer. First of all, your trances benefit your allies in addition to yourself. Next, your very formidable crowd-control skills help to keep attacks from large numbers of monsters from becoming overwhelming. Your nightmare pet helps with the crowd control by confusing large numbers of monsters, and, more importantly, its mastermind ability allows it to greatly strengthen not only your own pets, but those belonging to your allies as well. Combined with the damage output that you'll be capable of with skills like psionic touch and distort reality, the seer is exactly the sort of character you'll want to bring along on your next multiplayer adventure
