Your biggest Doh moment...

[Corinthian]

My biggest "Dohh!" moment came in one of my first games. I had to stop a big mannish communion. I did not have many tools at hand but I eventually came up with a bold plan to have a mage cast Foul Vapors. I had previously noticed that the enemy mages used the spell "invulnerability" to protect themselves. This spell also gives the recipient 100 points of poison vulnerability so the plan was to distract the communion with all manner of spread out chaff while the enemy died from poison and suffered a Pyrrhic victory.

Everything worked wonderfully! Although I lost a lot of troops, the enemy mages were also dying in droves! But they did not stay down! Apparently the enemy had snuck in a Death mage that cast Life after Life on the army and every fallen mage rose again as the undead. Not only did I waste a huge amount of troops in order to screen my mages, the only thing I managed to cut down was the enemies upkeep costs, by a huge amount! It was terrible.
