School of Somnomancy

The somnomancers are an idiosyncratic bunch, given to fancies, daydreams and odd sartorial choices, and it is no surprise that they are rarely accorded any respect by mages of other schools. Although their obsession with sleep is occasionally useful, such as when someone needs to be hypnotized or must have their dreams interpreted, it is more often a source of humor – much to the chagrin of so-called 'pajama-mages'!

Soporific Savant

When you select this school at 2nd level, you gain some degree of control over your own sleep patterns. From now on, you only require four hours of sleep in a long rest and cannot be put to sleep by magic.

Careful Somnomancy

Also at 2nd level, you add the sleep spell to your spellbook if it is not already and you can freely choose the order in which creatures are affected by a sleep spell you cast.

Deep Sleep

Beginning at 6th level, whenever you cast sleep, whenever a creature is under the effects of sleep and is damaged instead of waking up they instead re-roll the save. Additionally, the die to determined the health pool gains an additional 2d8s. At 10th level they become 3d8s and at 14th level they become 4d8s.

Dreamspeaker

At 10th level, you add the spell dream to your spellbook if it is not there already. When you cast this spell, the messenger may jump between up to 12 creatures (each makes their saving throw against the spell separately), conversing with any or all of them. They can only appear monstrous  to one of the targets, however, and the spell ends immediately after that option is utilized.

Fiteful Slumber

When you reach 14th level, you can give creatures that you put to sleep terrible nightmares. At the start of their turn, you can choose to make any creature that is under the influence of a sleep spell that you cast suffer 3d6 psychic damage. This damage cannot wake a creature up, nor can it reduce a creature below 1 hit point.
