【法术问题】换脸术的持续时间：永久，对吗？有没有笔误的可能？

[我因昵称中有某个名字而被扣了2......]

↓这些描述看上去挺像是在说“立即” 

换脸术是一个永久性的效果，这个法术不会留下灵光，也不会被任何侦测效果看穿。

除了贴上假面，换脸术还可以用来移除已经贴上的脸。这是除了高等变形术，奇迹术与许愿术外唯一可以办到这类效果的法术。

也许大概有可能吧，但是我没找到相关规则帖子，只找到一个和你一样疑问的帖子

DESCRIPTION

This spell allows you to add a creature’s stolen face to or remove such a face that you’ve already applied from your own. Before casting this spell, you must remove the face and eyes of a creature that has been dead no longer than 1 minute per caster level and place it over your own. Once you cast transplant visage, the creature’s stolen skin magically melds with your own, making the expressions and eye color on your new face seem perfectly natural. Your new appearance grants you a +10 bonus on Disguise checks. Because the alteration made by transplant visage is permanent, there is no residual magical aura, and your new appearance is not recognized by detect spells. Transplant visage may be cast innumerable times, allowing a single caster to wear layers upon layers of stolen faces. However, only the topmost face is visible at any one time.

Transplant visage may also be used to remove a previously stolen face. This is the only way to remove a face short of using greater polymorph, miracle, or wish. When used in this way, transplant visage causes the topmost face to flake off and crumble into dust. A face so removed may not be reused. If the caster is wearing several stolen faces when the topmost face is removed, the next face down is revealed, and may be used as normal.

一般来说，这是因为设计师没有参加过滥强讨论。
分不清“立即”才是真正的永久。
