I have a dragon, trained and ready for combat. several, actually. To weaponize them, I was considering making the walls of the entrancve traphall out of drawbridges, and pasture the dragons on the other side, then pull the lever to release the drawbridge, exposing the nasty sieges to dragonfire, but I have a couple questions:
Does dragonfire melt traps that are on the ground? will it melt bridges that are not raised? how many dragons should I use? Should I build dragonfire sniper towers instead?
