"It will take time, yes. Don't be too hard on yourself if the learning curve is steep." Istredd is being genuine with that. He can't imagine being completely new to everything that is natural to him, and he also needed time to adjust to being captured to another sphere. For him, it's been an experience that he would actually choose, given the chance, but that is not true for everyone.

He nods though at the next part. "Yes, there are some Summoned here who train people in combat. Lucifer is one of them and Natasha Romanoff. She is a redhaired woman who is new to using magic herself, and very grounded." She'd probably be of great help to John, in his opinion.

"You should speak to her if you get a chance, perhaps you can fill holes in their training. Yennefer and I teach different classes." Meaning that John could teach a set of skills the other two do not. It's something to do, and that can be very helpful in the start of this.
