[Harry Potter] Do boggart replicate the power of those they turn into?

When Boggart turn into Dementor it look like it has a weaker version of actual dementor's draining. Does that mean they actually replicate that power? what if my fear was something that have instant effect like medusa, will I turn into stone? or if I fear Azathoth, will they also replicate weaker version of azathoth's power?

They have the ability to weakly replicate the powers and abilities of whatever they take form of, how weak is hard to say.

The dementor boggart was weak enough for Harry to train on, but still strong enough to make him pass out.
