One extra-class ability and why game

[Flying Mullet]

I don't know how well this game will work, but it's worth a shot. The way it's played is I'll start by listing a class, the next person should imagine themselves playing a single-class challenge with this class. The question to them is: What single ability from another class would you choose to use with your single-class characters and why?

For an example I'll start with the class of Summoner. If I could choose one single ability it would be Short Charge from Time Mages so summons can be cast quicker. The next poster should imagine themselves with a group of Time Mages and state what single ability would they like to take advantage of and why.

Rinse and repeat.

Time Mage. Go!

Blade Grasp, So your Time Mage only has to worry about magic and special abilities but doesn't have to worry about being taken down by heavy hitters.

Samurai

[Zechs]

Chakra, so it takes more strategy to kill them off.

Monk.
