Here we go! The final showdown between Gelu and Xeron! It all comes down to this. In To Kill A Hero, Gelu, Roland, and Catherine must lead the remaining conflux armies into the heart of Eeofol and defeat Xeron once and for all!
It's a very straightforward scenario. You don't need to capture any towns or unlock any border guards. Destroy Xeron's army and victory is yours!
Catherine and Roland begin the scenario in the southwestern corner of the map. Gelu starts in the northeastern corner. You can initiate a pincer attack on the poor Eeofol army.
Xeron is a very high level hero with a powerful army. The Armageddon's Blade artifact allows him to cast the expert level Armageddon spell without damaging his own troops. Thankfully, the enemy AI doesn't cast the spell every turn.
Xeron can be found guarding the inferno city in the center of the map. He seldom ventures outside of the garrisoned area. On the downside, you won't be able to capture the last inferno and wait for Xeron to abandon his army. However, it also means Xeron won't harass your towns with his overpowered artifact. You'll be able to capture all of the surrounding infernos without fear of retaliation.
How difficult you find this scenario depends on how much you prepared your heroes in earlier scenarios. If you spent a lot of time visiting stat modifiers and learning spells such as Town Portal, Resurrection, and Fly, the scenario will be easy to complete. If not, prepare for a long, painful adventure.
My final battle with Xeron was rather repetitive. I sent phoenixes to attack Xeron's melee stacks and then repeatedly cast Resurrection. Meanwhile, my sharpshooters slowly chipped away at Xeron's arch-devils and pit lords.
Xeron and the Sons of Erebus have been defeated! Armageddon's Blade has been captured! Peace has been restored! That's the end of the campaign, right?
What's this? There's still one more map. Hmm... I wonder what else Lucifer Kreegan has up his sleeve.
