Quick Cast: Yes
Requirements: Chanting for several minutes and some magical herbs. A witch or warlock need only gesture and say a few words.
Effects: This spell causes the air to harden into a barrier as strong as an inch of steel plate, the barrier is approximately 20 feet high and wide and is invisible unless touched (in which case the air seems to “ripple”), if cast in a smaller space the barrier will re-size itself. The barrier lasts for one minute per success level of the spell. The spell can be cast anywhere within 100 feet of the caster but it will only cast in open space it can not displace matter.Buffy TVS Spells
