施法 Spellcasting本节扩展了玩家手册和地下城主指南中所提及的施法规则,并提供了详细说明和新的选项。
This section expands on the spellcasting rules presented in the Player's Handbook and the Dungeon Master’s Guide, providing clarifications and new Options.
察觉法术的施展 Perceiving a Caster at Work许多法术展现出明显可见的效果:如火焰爆炸,冰墙,传送等等。其余的某类法术,如魅惑人类一样,没有任何可见的、可听见的、或其他可察觉其效果的迹象,并且很容易被不受其影响的人所忽视。正如《玩家手册》中所提到的,你通常不知道一个法术已经被施放了,除非这个法术产生了一个能够引起注意的效果。
但是施法的动作呢?是否有可能有人正察觉到一个法术正在被施放于他们的面前?要被觉察到,这次施法必须包含言语,姿势或材料。无论使用的是在法术描述中所指定的材料物件、材料包或者法器,该材料成分的具体形式对于感知结果而言并不重要。
如果对法术成分的需求已经被一种特殊的能力所取代,比如法师微妙的法术特性或者许多生物所具有的天生施法能力,那么施法是不可察觉的。如果一个不可察觉的施法产生了一个可感知的效果,通常不可能在没有其他证据的情况下确定施法者是谁。
Many spells create obvious effects: explosions of fire, walls of ice, teleportation, and the like. Other spells, such as charm person, display no visible, audible, or otherwise perceptible sign of their effects, and could easily go unnoticed by someone unaffected by them. As noted in the Player’s Handbook, you normally don’t know that a spell has been cast unless the spell produces a notice- able effect.
But what about the act of casting a spell? Is it possible for someOne to perceive that a spell is being cast in their presence? To be perceptible, the casting of a spell must involve averbal, somatic, or material component. The form of a material component doesn’t matter for the purposes of perception, whether it’s an object specified in the spell’s description, a component pouch, or a spellcasting focus.
If the need for a spell’s components has been removed by a special ability, such as the sorcerer’s Subtle Spell feature or the Innate Spellcasting trait possessed by many creatures, the casting of the spell is imperceptible. If an imperceptible casting produces a perceptible effect, it’s normally impossible to determine who cast the spell in the absence of other evidence.
辨识法术 Identifying a Spell有时一个角色会想要识别一个对方正在施放或已经施放的法术。为此,角色可以在对方施放法术时使用他们的反应来识别法术,或者他们可以在对方施放之后使用一个动作来识别法术的效果。
如果角色感知了施法、法术效果,或者两者都感知到了,角色可以通过反应或动作来做一个智力(奥秘)检定。DC = 15 +法术等级。如果该法术以类法术的形式施放,并且该角色是其同类的成员,那么该检定将带有优势。例如,如果施法者以牧师身份施放法术,另一个牧师在这次识别法术检定上带有优势。某些法术在施放时不会与任何职业发生冲突,比如当一个怪物使用其固有的施法特性。
这个智力(奥秘)检定代表一个事实,即识别一个法术需要敏锐的头脑及熟悉施法的理论和实践。即使对于一个施法能力是感知或魅力的角色也是如此。能够施法本身并不能让你熟练地推断出别人施法时在做什么。
Sometimes a character wants to identify a spell that someone else is casting or that was already cast. To do so, a character can use their reaction to identify a spell as it’s being cast, or they can use an action on their turn to identify a spell by its effect after it is cast.
If the character perceived the casting, the spell’s effect, or both, the character can make an Intelligence (Arcana) check with the reaction or action. The DC equals 15 + the spell’s level. If the spell is cast as a class spell and the character is a member of that class, the check is made with advantage. For example, if the spellcaster casts a spell as a cleric, another cleric has advantage on the check to identify the spell. Some spells aren't associated with any class when they’re cast, such as when a monster uses its Innate Spellcasting trait.
This Intelligence (Arcana) Check represents the fact that identifying a spell requires a quick mind and familiarity with the theory and practice of casting. This is true even for a character whose spellcasting ability is Wisdom or Charisma. Being able to cast spells doesn’t by itself make you adept at deducing exactly what others are doing when they cast their spells.
无效的法术目标 Invalid Spell Targets一道法术会具体指明施法者可指定的目标:任何类型生物、特定类型生物(比如,类人生物或野兽)、一个物件、一个区域、施法者本身或其他什么东西。但是如果一个法术的目标不是一个有效的目标会发生什么呢?例如,有人可能会对一个被认为是类人生物的生物施展魅惑人类,而不知道目标实际上是个吸血鬼。如果出现此问题,请使用以下规则处理。
如果你对某人或某物施放了一个不能被该法术影响的法术,那该目标将不发生任何事,其结果等同于其豁免检定成功,哪怕它并未进行过任何一次豁免(不要表露任何该生物是无效目标的暗示)。否则,你就会视为意识到该法术对目标无效。
A spell specifies what a caster can target with it: any type of creature, a creature of a certain type (humanoid or beast, for instance), an object, an area, the caster, or something else. But what happens if a spell targets something that isn’t a valid target? For example, someone might cast charm person on a creature believed to be a humanoid, not knowing that the target is in fact a vampire. If this issue comes up, handle it using the following rule.
If you cast a spell on someone or something that can’t be affected by the spell, nothing happens to that target appears to have succeeds on a saving throw, even though it didn't attempt one (giving no hint that the creature is in fact an invalid target). Otherwise, you perceive that the spell did nothing to the target.
