You can’t apply the same metamagic feat more than once to a single spell.
The metamagic rods function the same for any
spellcaster—they allow her to apply a metamagic effect “on the
fly” when casting the spell to be affected.
既然超魔棍子是apply metamagic effect, 那么根据上面那条, 强效棍子和强效专长是不能一起对同一个法术生效的.
but it is permissible to combine a rod with metamagic feats possessed by the rod’s wielder. In this case, only the feats possessed by the wielder adjust the spell slot of the spell being cast.
至于这条, 说的应该是不同的超魔效果, 不能违背第一条的原则...
个人意见,恩, 不过至少我会这么判.
好吧其实我是在补充sheepy君最后那句
