Repulsion

Repulsion was an abjuration spell that prevented creatures from approaching the caster. It was a common spell in the Realms.

Effects
Repulsion created an invisible, mobile field around the caster. This field made it impossible for other creatures to get near the caster.

The size of this field was at the caster's discretion on casting. Creatures who were within or were trying to enter the field were unable to enter it or were repelled but were otherwise not restricted in their actions. they could still fight, cast spells, and so on.

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

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.

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.
