Searching for how to give a rogue I'm building a sort of eidetic memory, I came across many posts throughout the net about using the feat Keen Mind as a way for wizards to negate having to worry about it in battle. Not having understood Keen Mind's definition in this way, it got me to look at feats in a new way to see how they might be used.
[...] You can accurately recall anything you have seen or heard within the past month.
[...] If you can see a creature’s mouth while it is speaking a language you understand, you can interpret what it’s saying by reading its lips.
[...] You can mimic the speech of another person or the sounds made by other creatures. You must have heard the person speaking, or heard the creature make the sound, for at least 1 minute. A successful Wisdom (Insight) check contested by your Charisma (Deception) check allows a listener to determine that the effect is faked.
Given that spells are broken down to three aspects, Verbal, Somatic, and Material, where the verbal aspect is more about the sound than what's said, could the three feats listed above combine to grant a wizard the ability to replicate any spell he witnesses?
I realize that spells are more complex, so the wizard would have to have the spell slots available, an arcane focus to take care of the material part (limited by the conditions of an arcane focus) and would have to have some insight on how that spellcaster might sound beforehand (granted this can be done by asking around the Magic Guild to show off their favorite spells, and applying what you learned to similar races/classes), but in general, am I correctly understanding how a wizard could use these feats to, in a way, use the enemy's skills against them?
