I had lost Green Seer to an immediate Death Touch by Wraith. I was building up my mana to fire Giant Spider when I had a match 4, Kraken applied his damage from Tentacles and . . . . .
It did that animation where a troop (not sure which one) jumped from enemy troop to enemy troop freezing them and applying Deathmark to each of them.
I didn’t put this in support (maybe I should have) because I ended up winning the match but none of my team apply Deathmark or have Frozen. Definately a quirk.
Just thought I would let @Sirrian and @Nimhain and the rest of the team know what happened. None of the Deathmark’s killed anyone and they didn’t get any match 4/5’s for me to see if the Freeze was triggered.
