So, would these be at will, or maybe you could have it be "readying" X number of words?
So, at 1st level, you can have 3 words readied, but you gain another every, oh, I don't know odd level thereafter?
So you would get 12 words at 20th level?
I'm really thinking that you shouldn't mix up Point values and the Words themselves; or, allow specialization in the words, which increases their point value (ever played Lost Magic? In that game, the more you played with a given rune, the cheaper that rune got. Considering that, like with what your trying here, you eventually combine runes, a cheapening (or in this case, increasing of the value), would be wondrously effective.)
