One of the most evil entities an adventurer may come across, are the creatures
that inhabit the planes of hell, such as devils and demons. All of them are
fierce and dangerous opponents, capable of great destruction and carnage. To
combat such incarnations of malevolence, there exists a rite that attacks the
very core of their being, its link to existence on this plane. While this
spell is usually not powerful enough to banish them outright, it can cause
great stress and pain as the demonic entity must spend effort and energy in
order to maintain its physical form on this plane of existence. 
Banish demons is the single most powerful dispel spell, but it can be used
only against demonic entities such as devils and demons. When successfully
cast, the divine purifying forces gather inside the caster, ultimately
violently erupting through caster's relic in one big burst, exploding upon the
demonic target. Knowledge of dispelling is required to fully master this
spell. Every successful cast is a tribute to the God Las, and will not go
without a reward.
