Once a Round :
Reduce 1 attack of an enemy by 1, that enemy gains Cumbersome this turn. Put this skill token in the centre. Until the start of your next turn, any player may return it to you, face down, to reduce 1 attack of an enemy by 1 and give that enemy token Cumbersome that turn.
Cumbersome = In the Block phase, you may spend Move points; for each Move point spent, the attack is reduced by 1 for the rest of the turn. An attack reduced to 0 is considered successfully blocked.
