Repulsion

Repulsion was an abjuration spell that prevented creatures from approaching the caster. It was a common spell on Toril. It had a clerical version developed by the drow and an arcane version developed by the Netherese arcanist Prug.

Effects
As mentioned above, the repulsion spell had two versions. Both made it impossible for creatures to get near the caster, but there were a few differences.

One difference was repulsion spells' difference of the area of effect. The arcane one created an invisible, mobile field, radius of which was at the caster's discretion, around the caster. This field made it impossible for other creatures to get near the caster. The clerical version created a ten feet (three meters) wide path that made creatures walk away, which was also marked by black harmless flame. This path's direction could be changed at the whim of the caster.

Repelled creatures could not get near the caster but were otherwise not restricted in their actions. they could still fight, cast spells, and so on. The divine version actually made creatures move away from the caster.

If the caster moved closer to a creature in order to repel it, nothing happened.

The clerical version ended prematurely when the caster entered combat, cast another spell, or did anything complicated.

Material components
Repulsion required somatic and verbal components as well as a pair of small iron bars attached to two small canine statuettes, one black and one white, as an arcane focus if cast as an arcane spell, or a divine focus such as a holy symbol a miniature sword (a dagger or knife would do too), and a flame, spark, hot coal, or ember if cast as a divine spell.

History
The Netherese arcanist Prug is given the credit for the creation of this spell in -1815 DR under its original name Prug's repulse. Throughout the Age of Humanity this spell required a pair of small iron bars attached to two small canine statuettes, one black and one white as material components. After the Time of Troubles, the spell was altered so that the pair of small iron bars attached to two small canine statuettes were now an arcane focus items.

Realmslore
During the age of humanity the somatic component of this spell was to hold the two canine statuettes, one in each hand, bring them together in front of the caster and then draw ones hands apart violently as the material components were consumed in a pulse of light.
