Ronghand

Summary
Ronghand is an electric based spell that changes which hand is the targets dominant hand. The spell operates by shooting an electric signal into the arm, modifying the muscle movements and connections to the brain, forcing the other hand into becoming the dominant hand.

Due to the specifics, it can only be cast on one target at a time, with a short cooldown between, and will last anywhere from 30 seconds to 6 hours.

Uses
Ronghand is extremely useful in one on one combat, as casting mid battle will cause temporary confusion allowing openings, and as such will typically be fired as often as possible mid battle.

When used stealthily, it can also be used to interfere with those operating heavy machinery, vehicles or mounts, triggering massive accidents.
