I tried using an ability that gave shield bonus before dice are rolled, but the attacking hero, trenloe removed my defense die on my monster. He argued that since I wasn't rolling dice, that I couldn't give any bonuses, since it says before rolling dice. My counter to that was rolling dice is more like a step or phase, so I should be able to use it. I'll sum up the situation:
Trenloe Heroic Feat on a one def die monster Me: Aurium plating on a now no defense monster
I'm pretty sure i'm correct on this one. Also, F*** Trenloe and his tankiness.
