作用
检查你选择的物品组中你携带或穿戴的第一个物品是否可以使用，即你满足其等级要求且它不在冷却中。勾选“未携带时也检查”后，即使你没有该物品，也会检查物品组中的第一个物品。
为什么会用到它
Check that an item is ready to use: you meet its level requirement and its cooldown is up (or ends with the global cooldown). Add it to steps for potions, Healthstones, explosives and on-use trinkets so they are only suggested when usable; the step's own ownership, usability and range checks still apply. With Check If Not Carrying, the first item in the set is checked as though you had one, which suits a reminder that the Healthstone cooldown is ready so you can get a new one.

设置
条件编辑器中每项设置的含义，取自游戏内的帮助。
物品组 - This is a list of items to look for in your inventory. This list is ordered, the top found item in the list that you are carrying or wearing is what will be used in this condition. NOTE: this will NOT search for ANY item in the list that matches this condition, only the first item found will be used in this condition.
You can choose from either a pre-defined Item Set, by picking it by name from the drop down menu. You can edit these using the 物品组 configuration menu. Any item set in cyan is a global item set available to all your characters, otherwise they are available to this character only. If you do not want to set up a reusable item set, you can select 自定义 to specify an ad-hoc item set.
Edit - Edit the contents of the item set. If you have selected a pre-defined item set, you will be editing that item set, which may affect other usages of that item set (including on your other characters if it is a global item set). An item set must have at least one item in it for this condition to be considered valid.
物品组按优先级顺序检查。背包数量使用第一个携带的候选物品，而不是总和。可用性、距离和冷却检查使用第一个携带或已装备的候选物品。缺失或受限的观测保持为不可用，在 NOT 下同样如此。
“物品可用”会检查所需等级和已启用的物品冷却。只有当冷却随可读的公共冷却一同结束时，正在进行的冷却才算符合。此条件不会绕过动作隐含的拥有、可用性和距离检查。
未携带时也检查 - Check the availability of the first item in the item set as if you were carrying it, even if you are not.
