This spell is a part of the Fang spell chain and can be found in the Fang rune stone.
The necromancer does not go looking for Pain. That is the first thing they will tell you, and they mean it. Pain finds them the way it finds everyone; quietly, uninvited, arriving in a moment when the necromancer is least prepared for it. The difference between a necromancer and everyone else is what happens next. Everyone else flinches away. The necromancer goes still, listens, and begins to understand that what they felt was not an enemy. It was an introduction. Fang is that introduction made into a weapon.
When the necromancer first reaches for this spell they are not yet in full command of what answers. Pain responds to being called with an immediacy that is almost startling. Without warning two sharp concentrations of death energy forming from nothing, curved and precise, carrying all the cold intention of something that knows exactly what it was made to do, cross the distance to the target without ceremony and strike, each one dealing its damage as pure magical force, leaving no wound that can be seen but something that is felt long after the moment of impact has passed. Each fang deals 2d4 damage to the target, for a total of 4d4 magical damage. The target may be able to evade the first fang, but not the second. Pain is a certainty that can not be avoided. Pain asks something small in return for this first offering. The necromancer loses 1 Power beyond the casting cost as Pain reminds them that this is not a one-sided arrangement. It is instead the signing of a life long contract between the caster and the source of Pain itself.
Weapon Effect: Fang
Upon Critical Hit the weapon damage is split equally, so that should the target evade the strike, it will still receive half the intended damage.
