question about black dragon's rain of fire ability

[Zechnophobe]

Sorry, DG, this is not accurate. The AI only flies along the closest path. However sometimes that path will involve a quasi zig-zag if you are up against the edge of the map (Some maps have weird edging right, like in Ultrax).

The best use I have found for this ability is to have a black dragon start its move up against the far right side of the map, either at the top or bottom, and then move either bottom to top, or top to bottom. You will blaze out a path that will 'hug' the far right side of the screen... normally where a lot of baddies are sitting. Not to hard to get 4 or 5 hits with this technique.

Also remember you can move without ending your turn in this game. So you don't always want to activate the ability starting from your original Hex. Move to the correct location, and then start blazing. It is a very strong ability.
