I ran off to a challenge battle against a spectre army. It was only rated at ~20% strength, and my army was ~40% strength, so I thought it would be no problem; I'd been winning 50% vs 40% battles with almost no casualties, after all, so 20% vs 40% should be a piece of cake.
And at first, it
was easy. The first wave of ghostly wolves fell easily to my arrows and heavy infantry. My morale was fine, as my cavalry had secured half the victory points. Then their hero, along with his unit of mounted Spectres, charged my lines. 30 seconds and one Spearman dogpile later, he was down to 1/3rd health, and I thought the battle was won with nearly zero casualties.
Then he cast Breathstealer, a spell I hadn't seen before. I only knew the description, which implied it was a life-stealing spell.
He immediately jumped back to full health and remained there for the rest of the fight. I couldn't reduce his health in the slightest; he, meanwhile, proceeded to decimate team after team of my best troops. Half my units were retreating with a handful of survivors; at least one had been eliminated outright. Any team that so much as touched him in melee collapsed (and, when your opponent is mounted, there's no way to
avoid melee combat!). When my hero hit half health and the enemy commander was
still at near-full health, I knew I was screwed; that one bastard, on his own, had dealt more damage than most full-size human armies could.
King Arthur: The Role-Playing Wargame; horray for Steam sales! Admittedly I'd sent a piss-poor hero along - my main armies were several seasons away, and since the fight was supposedly easy I didn't consider that I'd sent a single economy-focused hero and a somewhat-undertrained army. Whoops.
