I am currently testing various cards Ive deemed underpowered and I am currently running a campaign where I am using this mod.
I am currently using it with the text: "[1 strain]Exhaust this mod when you declare an attack."
My thoughts were this. A black die cancels an average 1.5 dmg, not counting the evade (1.67 if the evade cancels 1, 1.83 if the evade cancels 2). When you compare to spread barrel which does a straight 1 dmg, I thought the 1 strain would be a fair cost for the additional damage above the 1 dmg that you may get.
On the table however, it just felt really really strong but maybe my perception was skewed because I was using it with Onar, who has strain for days. I'm not sure.
2 strain is too much I think. It could still work on Onar, but that is probably it.
Any thoughts?
