Once a Round: Choose a color other than gold and gain a mana token of that color. Put this Skill token in the center and mark it with a second token of that color. Until the start of your next turn, other players get wound when they use mana of any other color on their turn, limit 1 Wound per color for each player. (if they use gold, count it as the color it is used for.) Then take this token back and flip it.
