Spell是什么相信无疑问。
至于spell-like abilities
MM的解释:
Spell-like abilities are magical and work just like spells.
DMG的解释:
Spell-like abilities, as the name implies, are spells and magical abilities that are very much like spells.
Rules of the Game的解释:
The term "spell-like ability" has been part of the D&D game for many years, and it still retains its essential meaning: A spell-like ability is a magical trick that works exactly like a spell of the same name.
据此我认为魔法武器的附加神圣伤害这种东西既不是Spell也不是spell-like ability,“Only spells and spell-like abilities are subject to spell resistance”,因此我认为SR无效。
而那些描述中说明了“如同XXX法术效果”或者本身就与法术同名的效果,就可以认为SR有效。
至于SAVING THROWS AGAINST MAGIC ITEM POWERS那段,我不认为其意思是指“所有魔法物品”都产生法术或类法术效果,而是说明“能产生这类效果的魔法物品”的SV是如何运作的。佐证是Rules of the Game 相同小标题下的说法是“Most magic items produce spells or spell-like effects. ”(大部分魔法物品产生法术或类法术效果)
最后,SU效果是“cannot be dispelled ”,而魔法物品也并不是被dispelled,只是跟在AMF里被压制一样而已,因此我认为Dispel Magic可以短暂压制魔法物品效果这点或许可以作为魔法物品不同于SU的证据,但显然无法作为魔法武器附加伤害这类效果也是属于Spell或SP,或者会受SR影响的证据。
