[3R]掩飾施法能掩飾到什麼程度

[月伶]

出自完美流氓的技法：

掩饰施法(Conceal Spellcasting)[操作技法]
你可以施法但不引起别人注意。
先决条件：专注1级，手上功夫5级，法术辨识1级
效果：你可以掩饰你的施法动作，使它看上去不像是在施法。作为你施法动作的一部分，进行一次手上功夫检定，对抗观察者的侦查检定。如果你成功，观察者将不认为你在施法。他将不能对你的施法进行借机攻击，或者反制你的法术。

這個動作是只限姿勢還是包括語言也可以不被察覺？
正在抉擇有限的擴展機會要怎麼用

Conceal Spellcasting [Manipulation]

You can cast spells without others noticing.
Prerequisite: Concentration 1 rank, Sleight of Hand 5 ranks, Spellcraft 1 rank.
Benefit: You can cast a spell without revealing that you are doing so. Make a Sleight of Hand check as part of the action used to cast the spell, opposed by the Spot checks of onlookers. If you are successful, an observer can’t tell that you’re casting a spell. That observer cannot make an attack of opportunity against you for casting, nor can it attempt to counter your spell.

以上，根据原文是让别人看不出你在施法
