Verbal magic
From AmtWiki
A form of Magic. Text from the Rulebook Glossary.
Description
These ranged spells utilize spoken components and need not touch or hit their target. Verbal magic can only be cast on targets the caster can see. There is no way--other than being immune, out of range, or not being seen--to avoid Verbal magic. A weapon can usually be hidden behind one's back to prevent magic such as Heat Weapon from being able to target it.
