Is Ghost Riders too powerful ?

[apoger]

At level 9 research you should expect good effects.

Keep in mind that this spell won't do much damage to a serious army and furthermore it doesn't capture the province. It's great for damaging/killing weak forces, but again for a level 9 spell you expect some beef.

At the high spell levels there are a many spell effects that are potential game changers. This is just one.
