I am willing to allow Kirinke to change her class to wizard if she would prefer, or any other class for that matter if she thinks it's a better idea. Everyone's just leveled up and we haven't had a combat encounter yet, so I don't have a problem with her switching the class she'd be taking this level if she wants. A couple stipulations though:
If she chooses to go wizard: The Mage Hand incident never took place, because it wasn't memorized. She could have dreamed it though. There is really no limit as to what your character can dream obviously, as long as they don't believe everything they dream will come true for their character in-game...
If she chooses to stay sorcerer: The Mage Hand could have taken place, but from now on Kirinke must remember that the spell is not powerful enough to push a dwarf down, or anyone else for that matter.
If she chooses to stay ranger for now/go fighter/etc.: Anything else, the spell did not happen, she could have dreamed it as above, a subconscious foretelling of her ability to learn magic perhaps.
Regardless of which you choose for Alnis, I'm not all that hot on the issue of her manifesting these powers in those special circumstances, if she cannot cast them naturally. If she stays sorcerer like she is now, she has no problem casting level 0 spells (cantrips), so she does not need to be spurred on by a shock or being knocked unconscious to use them. Any spells higher level are out of the question, in favor of character balance. (It would not be quite fair to that goblin if both Alinis & Elyas cast magic missle at it before Alinis rightfully could for instance.
