Weem:
Thanks for making those great cards. I'm going to suggest that my group try them in our next session.
May I make a few suggestions?
1. For ongoing damage, an icon (you make great icons!) or a color to indicate the type of damage would be helpful. Green for acid, blue for cold, reddish orange for fire, etc. The blood splatters are great for untyped damage.
2. It might be helpful to have a place on the card to note resistance to the damage -- it's easy to forget you have it. (Players are eager to start their turns and may rush through the ongoing damage phase without thinking, or else have to inflict it later when the DM says "hey, did you remember to...")
3. It would be nice if there were a place to indicate the duration of conditions.
4. Also -- save bonuses or penalties?
I know, it's getting complicated at a certain point. Maybe a few extra cards that one can pair with the conditions. For example, Stunned card paired with "-2 on saves against this condition".
Just ideas.
