4e规定的很详细了,仔细研读就好
Arcane Fire专长描述如下: When you hit a target with an arcane fire power,that target gains vulnerable 5 cold against the first arcane attack power you use against it before the end of your next turn.
于是,第一个问题,描述中写道: hit a target,hit在4e中解释为命中,于是触发或者使用不算命中,只有带有arcane,fire关键字的威能命中才算
第二个问题涉及warlock's curse的定义,Once per turn as a minor action, you can place a Warlock’s Curse on the enemy nearest to you that you can see. A cursed enemy is more vulnerable to your attacks. If you damage a cursed enemy, you deal extra damage. You decide whether to apply the extra damage after making the damage roll. You can deal this extra damage once per round.
描述中If you damage a cursed enemy, you deal extra damage清晰地描述了,warlock's curse是额外伤害,curse本身没有arcane,cold属性,该伤害附属于攻击威能,因此单纯curse造成的额外伤害不能算作奥术冰伤害
