using dragon's breath
The projectile travels in a straight line - so make sure the path is clear.Dragon's breath has ranged impact (damage occurs to units within a specified impact radius) - this can make it very dangerous to use in proximity to your own troops.
Some creatures such as dryads are particularly vunerable to fire weapons, so dragon's breath will not only greatly damage them on impact, but will make them burn afterwards. More info on burning is available in the glossary.
