For our Wizards, on the other hand, we brought in a choreographer to help design new casting animation based on Finger-Tutting, a form of '90s street dance that focuses on intricate finger-work.
[Does this mean that Gale is in fact a fan of 90s-era Earthly hip-hop? According to my personal fan-fiction: Yes, specifically Wu-Tang.

So, two important points. One Give us fireball instead of just taunting us with references to the spell. Two can we get the voice actor to come back and add a bunch of Wu Tang references?

*Gale defeats an enemy* Gale - "Triumph"
*Gale prepares to attack* Gale - "Protect your neck!"
*Gale is getting attacked* "Bring the Ruckus"
*Gale sees a pit filled with rocks* "Gravel pit"
*Gale is confused by a puzzle* Its like the mystery of chess
*Gale figures it out* "Can it be all so simple?"
