Fighting dragons tips

[Zechnophobe]

Fight Fire with Fire. Take the Montero Dragon Castle fight, if you get some fire resist gear, stone skin, and the heal spell, you can kill all the dragons there with just a stack of red, and a stack of green.

Alternatively, know when to put your archers away. Yes, inquisitors and Beholders will get mauled by them, and do little damage back due to dragons being magic resistant as well. Put them in reserve.

Units that do poison damage do full damage to all dragons, especially effective against black dragons. Cast plague and/or helplessness to make the dragons far easier to damage. Plague can even be cast on black dragons.
