If {B} was spent to cast this spell, you may have target creature get -3/-3 until end of turn. If {G} was spent to cast this spell, you may have target creature get +3/+3 until end of turn. (Do both if {B}{G} was spent.)

如果使用溃疡饥渴时支付了{B}，则你可以使目标生物得-3/-3直到回合结束。 如果使用溃疡饥渴时支付了{G}，则你可以使目标生物得+3/+3直到回合结束。 （如果支付了{B}{G}，则两者都作。）
