Combat Challenge
In combat, it’s dangerous to ignore a fighter. Every
time you attack an enemy, whether the attack hits or
misses, you can choose to mark that target. The mark
lasts until the end of your next turn. While a target
is marked, it takes a –2 penalty to attack rolls for any
attack that doesn’t include you as a target. A creature
can be subject to only one mark at a time. A new mark
supersedes a mark that was already in place.
In addition, whenever an enemy marked by you is adjacent to you
and shifts or makes an attack that does not
include you, you can make a melee basic attack against
that enemy as an immediate interrupt.
首先说挑战 这里用的不是复数，所以如果龙裔战士用龙息攻击多个目标，或者其他多目标的攻击威能，不能进行标记吧？
同时蓝色部分说了，是用一个中断动作来插入一个MBA（不是OA），但是根据中断动作的说明和例子来看，挑战所来带来的这次攻击并不能取消目标接下来要做的事情
直觉动作的几个关键词
触发，每轮一次，应对和
中断
IMMEDIATE ACTION
Interrupt: An immediate interrupt lets you jump
in when a certain trigger condition arises, acting
before the trigger resolves. If an interrupt invalidates
a triggering action, that action is lost. For example,
an enemy makes a melee attack against you, but you
use a power that lets you shift away as an immediate
interrupt. If your enemy can no longer reach you, the
enemy’s attack action is lost.
借机攻击属于借机动作
OPPORTUNITY ATTACK: OPPORTUNITY ACTION
✦ Melee Basic Attack: An opportunity attack is a
melee basic attack (page 287).(借机攻击是基础近战攻击)
✦ Moving Provokes: If an enemy leaves a square
adjacent to you, you can make an opportunity attack
against that enemy. However, you can’t make one
if the enemy shifts or teleports or is forced to move
away by a pull, a push, or a slide.
✦ Ranged and Area Powers Provoke: If an enemy
adjacent to you uses a ranged power or an area
power, you can make an opportunity attack against
that enemy.
✦ One per Combatant’s Turn: You can take only one
opportunity action during another combatant’s turn,
but you can take any number during a round.
✦ Able to Attack: You can’t make an opportunity
attack unless you are able to make a melee basic
attack and you can see your enemy.
✦ Interrupts Target’s Action: An opportunity action
takes place before the target finishes its action.
After the opportunity attack, the creature resumes
its action. If the target is reduced to 0 hit points or
fewer by the opportunity attack, it can’t finish its
action because it’s dead or dying.借机攻击把目标打死了才能中断目标的动作
✦ Threatening Reach: Some creatures have an ability
called threatening reach. This lets them make opportunity
attacks against nonadjacent enemies. If an enemy
leaves a square that’s within the creature’s reach, or if
an enemy anywhere within the creature’s reach makes
a ranged attack or an area attack, the creature can
make an opportunity attack against that enemy.
所以在战士身边且被标记的生物，快步，或者攻击他人，最多只会被借机攻击一次，而不会被取消动作，也就是说只要这次借机攻击没有把目标打死，那么他的动作就可以完成
再来说卓越，
Combat Superiority
You gain a bonus to opportunity attacks equal to your
Wisdom modifier. An enemy struck by your opportunity
attack stops moving, if a move provoked the
attack. If it still has actions remaining, it can use them
to resume moving.
这里写的很清楚 to opportunit attacks 但是挑战带来的是MBA，所以不能获得感知调整值的加成
第二句话和挑战的第二个效果乍看起来似乎是有互动，其实不然
这里指明了是if a move provoked the attack.如果移动引发了你的攻击（通常都是借机攻击OA）那么你可以在命中这次攻击后让敌人停止移动。但是挑战的触发条件是快步或者不包含你的攻击，而且使用的是MBA。
所以这两个职业特性并没有“如果一个我标记的了敌人在我旁边移动，快步，攻击他人，我就可以借机攻击他，并将他的动作终止”这样的连锁combo。
总结下来就是：
挑战|Combat Challenge
在战斗中，忽略一名战士是危险的。每次你攻击一个对手，无论是命中或失手，你可以选择标记目标。标记维持到你下一回合结束以前。当一个目标被标记，除非该次攻击包括你，否则它的任何攻击都承受-2惩罚。一个生物一次只能有一个标记。一个新的标记将取代原来已经放置上去的标记。
另外，只要被你标记的敌人在邻近于你的时候快步或作出不包括你的攻击，你都能够以一个即时中断动作对它作出基本攻击。
挑战一次只能标记一个生物，被标记的生物如果在战士旁边快步或者做出不包含战士的攻击，战士就可以用中断动作进行一次MBA。（如果目标没死，那么动作继续，如果被这次MBA打死了或者进入不能继续动作的状态，比如昏迷，震慑什么的，那么目标的这次动作自然就被打断了，这个是中断动作的特性决定的 PHB268）
卓越战法|Combat Superiority
你获得等同于你感知调整值的加值到借机攻击上。如果一个敌人进行会遭致借机攻击的移动，被你借机攻击命中的敌人停止移动。若它还有保留的动作，它可以使用以重新移动。
加值只用于借机攻击，挑战引发的是中断动作性质的MBA，所以不加。同时，它只打断触发借机攻击的移动动作，攻击不能被打断（远程攻击，区域攻击触发的是OA而不是卓越，不包含战士的攻击触发的是挑战，打断的条件看上面，当然前提是被标记的目标，如果一个没有被标记的目标在战士面前使用近战攻击打其他人，则不会触发卓越，挑战，和OA）
不知道我说明白没有，或者有理解错误的地方，望高手指出，感激不尽，拜谢~！
