They chopped down his screamers but did little against Archaon, they were more a road bump, which worked!
I won the game, but tzeentch is tricky, I had 2 chances to cast hand of dust, 3rd and 5th battle round, both instant dispelled, the last 2 rounds was basically Archaon v nagash, I had 10 mortek left he had a blue scribe, neither were playing a part, he fluffed his king slayer attacks bottom of the 4th, both rolled 1 for priority which I kept, threw everything into him, leaving him on 3 wounds, he failed his saves, but got slayer of kings this time, i fluffed the roll for mortal contract, which would have been hilarious.
I’ll take the win, it played out how I wanted it too even if I lost bone daddy.
I really didn’t expect it to last 5 full rounds.
