Break enchantment can reverse even an instantaneous effect
I will address this point first, and have not brought it up because I thought it thoroughly debunked earlier by Thanee and me.
Firstly, simply because something
can do A, does not mean that it
will do A. Listed in the Break Enchantment spell is the ability to reverse an effect like
Flesh to Stone. The argument over BE's ability to specifically reverse FtS's effect should be held elsewhere, but it is enough to agree that BE
can reverse Duration: Instantaneous effects.
This is wholly different from saying, "Break Enchantment reverses all Insantaneous effects", because in that case,
every Instantaneous effect could be removed by BE. In such a case there would be a conflict with the BE language and the Feeblemind language. But that is not the language of the spell.
Feeblemind is a Duration: Instantaneous spell, yes. But it is not necessary that it should be removed
because it is instantaneous.
Consider both of these True:
Alan can hit curve balls.
Bill throws curve balls that nobody can hit.
Do you suggest that because Alan
can hit curve balls, he must be able to hit Bill's curve balls? There is no conflict between these two truths, nor is there in the relationship between Feeblemind and Break Enchantment.
Does that answer your issue regarding the "can reverse even Instantaneous effects" problem?
