Celenia D10 System CD10: Spell: Backdoor of Bypassing

The witch carefully draws a circle on wall that is made of stone or wood. The circle must be completed just as the recitation of the spell is finished or the spell will fizzle. If the spell takes effect, the wall inside of the circle will disappear, allowing passage. The stability and structure of the wall is not affected, as the passage is entirely magical. If the circle is broken, the spell immediately ends.
