Here's my proposal:
"It makes 0 sense that an enemy magically builds up 100% resistance to a hot, blazing wall of fire in front of them after walking 3 squares...
What if every step increased the enemies resistance to fire. Like how players build a resistance to Eni's heals. Doesn't that seem more logical? That way, the effects of firewall can't be taken advantage of, but the user can decide if he wants to keep the firewall out, while only hurting the enemy a minimal amount.
And then you could take it one step further and say that the enemy builds resistance to EVERY fire attack made on the board. So if another player attacks with fire, the enemy will have higher fire resistance. Make there be both positives and negatives to using firewall.
This way, if a player is alone, they can rely on there firewall to do most of the damage, or if their with other players, they might need to adapt their strategy.
I don't want to sound like a d***, but just limiting fire walls damage to only 3 cells per turn just sounds like a quick resolve to stop people from abusing it. There is 0 creativity used in developing a way to make fire wall more in depth and unique."
And there it is.
Please, feel free to write your own thoughts on how it should be revamped!
