超魔咒使这个3级职业能力是著名的翻译错误。
Metamagic Effect (Su): At 3rd level, an incantatrix can attempt to apply a metamagic feat she possesses to a persistent spell effect that is already in place. For example, she could use Extend Spell to extend the duration of a wall of force or Maximize Spell to maximize the damage dealt by a cloudkill. To use this ability, the incantatrix must be adjacent to or within the spell effect and make a successful Spellcraft check (DC 18 + [3 × modified spell level]. “Modified spell level” is the level of the spell slot that the spell would occupy if it were prepared with the metamagic feat applied. Spell slot increases for metamagic feats that were applied to affect the spell’s casting (such as Still Spell, Silent Spell, or Quicken Spell) do not count toward the modified spell level, but adjustments for metamagic that change the spell’s effect (such as Empower Spell, Enlarge Spell, or Widen Spell) do count.
For example, applying the Extend Spell feat to a wall of fire gives it a modified spell level of 5th (4th for the spell +1 for the Extend Spell feat), so the DC would be 18 + (3 × 5) = 33. If the wall of fire had been cast with the Silent Spell feat applied, the DC is still 33, since that feat applies to the spell’s casting, not its effect. On the other hand, extending an empowered wall of fire would give it a modified spell level of 7th and a Spellcraft DC of 39.
An incantatrix can use this ability a number of times per day equal to 3 + her Int modifier. Using this ability is a full-round action that provokes attacks of opportunity.
效果超魔（Su）：3级起，超魔咒使可以用一项她已有的超魔专长作用于已经存在的持续性法术效果。举例来说，她可以用法术延时来延时一道力墙，或是用法术极效来最大化死云术造成的伤害。要使用本能力，超魔咒使必须临近该法术效果或身处其内，并通过一次成功的法术辨识检定（DC 18+3*【修正后法术等级】）。“修正后法术等级 ”指的是该法术如果用所附加的超魔专长进行准备，则其将占用的法术位等级。影响目标为施法过程的超魔专长（如定发、默发、瞬发）不计入，但影响目标为法术效果的超魔带来的修正（如强效、增远、扩宽）应当计入。
举例来说，对一道火墙应用法术延时，其修正后法术等级为5（4级法术+1级法术延时专长），所以DC将是18+（3*5）=33。如果施展该火墙时应用了法术默发专长，则DC仍为33，因为这个专长影响的是施法的过程，而非法术的效果。不过另一方面，延时一个强效火墙会使得其修正后法术等级为7，并使法术辨识DC为39。
超魔咒使每日能使用本能力的次数等于3+她的智力调整值。使用本能力是一个会引发借机攻击的整轮动作。
如你所见，原来那个“翻译”比较惨不忍睹。
