My level 6 magus has just been magically transformed, his mouth and tongue becoming weird. This causes a 15% arcane spell failure chance, and, when combined with the 10% from my armor, is a dangerously high 25%. (The kensai archetype removes the standard magus's ability to cast in armor without penalty.)
One of my cantrips is ghost sound, which allows me to create the sound of people talking and stuff. Could I use a successfully cast ghost sound spell to cast other spells with vocal components to avoid the 15% arcane spell failure for having Cthulhu-mouth?
