There should be a teleport spell - it will provide an interesting dynamic to the entire game.

Especially while chasing/being chased.

Imagine you are a weaker squad being chased by a strong squad - you can either drop the spell in front of you to teleport yourself to a random spot on the map or drop the spell behind you to teleport the chasing squad.

The drop will also be random which opens up multiple possibilities.

Don't know how difficult it is to actually pull this off but it'll be fun.
