The camp of rail workers that we're protecting was attacked by a small army of zombie lizardfolk. Luckily, I had visions that hinted at an attack, and our preparations allowed us to have defenses in place.

When they arrived, it was literally 40 zombies and 4 shamans, with a dragonskull weapon that dealt massive ice damage.

Knowing I was the best hope to keep them back, I rushed forward, and turned undead... and literally blew up half of them.

Next round, I raced to the other flank and nuked the other side

Then to finish the conflict, when they turned their ice weapon on me, I raced up to the leader, Word of Radiance'd him to death, then aimed the death ray away to save our own hirelings at the cost of, like, significant necrotic frostbite.
