按照PHB,同一个超魔专长不能作用于同一个法术超过一次。所以正常来讲,如果默认法术反复出来的法术具有其他超魔的效果的话,这就是无意义的。
不过实践上讲,如果法术反复和法术孪生复制的法术都具有所有的其他超魔效果的话,实践上你可以把一个法术变成6倍效果(第一轮孪生为两个,这两个都自带反复法术所以第二轮会反复两次,第二轮反复出来的又都自带孪生法术效果)。
如果是某的话,某可能会判定这两个超魔具有特殊的互动方式(例如强效和极效的互动方式就被特殊注明了,强效出来的额外50%部分效果不会被极效),至少不会加倍到6倍的地步。(或者也可以考虑允许加倍为6次?毕竟要把一个法术附加一个+3环和一个+4环超魔并不是一件容易的事情,而且法术反复本身的效果很容易反制。)
虽然很想同意,然而并不是全部
If my wizard applies Energy Admixture (Complete
Arcane, page 78) and Maximize Spell to the same spell, does
he get a spell that deals double its maximized damage
(maximum normal damage in two different energy types)?
If he also applied the Twin Spell feat (Complete Arcane,
page 84) to the same spell would it duplicate the entire
effect?
Yes and yes. Assuming your character can cast 13th-level
spells—the slot required by a 2nd-level spell affected by these
metamagic feats—a scorching ray so affected would create two
sets of three rays each, with each ray dealing 24 points of fire
damage (4d6, maximized) and 24 points of a second energy
type (as appropriate for your Energy Substitution feat), for a
grand total of 288 points of damage . . . assuming all six rays
hit their target.
