Blatant is a tag I adapted from Scion 2e. It's let about forewarning and more about the aftermath. If you shoot someone with a firewand there will be a flash of light, a fwoom, and distinctive burn marks. You can still sneak up on someone with it.

Maybe getting rid of ambush would be a good idea to make in fit in Exalted more, and it would be a pretty strong downside.

Edit: In fact, I've made that change since it fits better with the Exalted ruleset.
