He would tell he can do it, but not necessarily how it works. Of course knowing that problem is solvable facilitates solution, but since we know the solution, we also know it would take time for Voldemort to find and use it.
So it is buffing, but with a time delay. That’s why I think it’s the simplest solution. Quirrelmort did start reading a book on physics, but is certainly far from understanding it deeply enough to do partial transfiguration.
This move would simply buy Harry time. It won’t solve the problem of Voldemort threatening the world, but will keep Harry alive, which is the objective of this quest.
There is tonnes of things Harry could infer and then tell him
OK, then use that to buy Harry’s own life. My idea was more about Harry buying his own life than telling about partial transfiguration.
No. He just learned to dispell Transfiguration without a wand when he dispelled the one on Hermione’s body.
