I pronounce it like the real word, but what I always wondered why they're in the game, I really don't use any of them except for Charge, Libra, and Steal. I would've used Shades of Black a lot more too, but most of the time when I use it it casts a low level black magic spell resulting in 0 points of damage to an enemy. The gambits to support them can also use a bit of work too.
