Don't cast spells of mass destruction kids!

Ciri had been trying to get into contact with Harry Potter for a while now, she'd thought it'd be rather easy to get the young teen alone to apologise and it seemed Harry was also trying to talk to her alone as well, the only problem was his ever present friends making things difficult, the Granger girl always interrogating her on what she wants from Harry and the Weasley trying to get in her pants, why he thought he was even remotely attractive to her would be a mystery she'd never solve but the problem still stands.

Either way she'd get to apologise eventually but she still felt it'd be better sooner than later... Maybe she'd get an opportunity when the tournament finally started. As she was now training under Reima to learn Pyromancy her confidence was steadily rising, every successfully thrown firebolt and cast combustion had her anticipating the future where she'd be able to throw around tsunami's of fire like Reima had been shown to be able to do. That wasn't all she was learning however as her Hogwarts education progressed she continued to learn more spells that'd help her in various ways, even first year spells like the tripping hex or counter spell would be incredibly useful in her fight against the Wild Hunt, she grins as she imagines Yennefer and Triss's faces when she performs unheard of magic for them.

She hadn't been slacking on her swordsmanship either however as that skill inparticular has proven to be incredibly valuable through all of her misadventures. Indeed her enthusiasm to get better only increased when she saw Reima wreath his sword in fire... Man that was cool, she hoped to be able to do that relatively soon, though for some reason he kept warning her to not channel her Elder Blood with Pyromancy or indeed any magic at all. He'd actually given her an example of why it was an incredibly stupid and reckless idea to actually do so.

Flashback :

Reima "Now, when you're utilising your Pyromancy flame do NOT, channel your Elder Blood."

Ciri "Er, why?"

Reima "Because, you'll either burn to death, combust, disintegrate, be turned inside out, teleport inside of yourself, teleport inside of someone else, teleport someone inside of yourself, cease existing entirely, be torn apart by spatial distortions, expl-"

Ciri "Ok, ok... I get it, but, why would that happen if I channelled it?" she asks confused.

Reima "Did Avallac'h not tell you anything?" he asks exacerbated at her lack of knowledge.

Ciri get's a sheepish expression, "He said it was something to do with the energy being attributed to space and time but... I wasn't really paying attention..."

Reima face palms, "Ok... Well, the basics of it are this, the Elder Blood is a type of magical energy that's attributed to Space and probably Time... I'm not really sure on the latter as I have yet to actually control or even affect time, apart from maybe perception of time but that's another matter entirely. The point is, the Elder Blood is incredibly powerful and if used in conjunction with something else, will give it the trait of time and space."

Ciri nods, "But why not try and control it if it's so powerful?" she asks confused.

Reima sighs, "I've been trying to, it's-it's just incredibly difficult to actually direct it in the same way every time... Even mixing it with fire, one of the easiest thing to manage as fire just uses the magic as fuel, it's still incredibly taxing mentally and magically... Look, I'll just show you what happens to an ordinary wizarding spell should you channel the Elder Blood." he says to try and finalise his point.

He points his hand at the Colosseum wall, "This'll be the stinging hex." he says and a Turquoise bolt fires from his hand, sailing and hitting the wall with no discernible effect.

Ciri "Nothing happ-" she's cut off as a ripple appears mid air and starts emitting some sort of electricity before imploding on itself and disappearing.

...

Reima glances back at Ciri, "A harmless stinging hex could probably kill someone if infused with the Elder Blood, but that's not all. I'll cast the same spell again." he says and shoots another Turquoise beam from his hand which impacts the same area, this time flashing into green light and vanishing, taking a layer off of the stone wall with it...

Reima "Imagine that on a human, if it's able to rip a layer of stone away from a wall, what would it do to someones skin?" he asks, but isn't expecting an answer.

Ciri "Fine, I won't play around with the Elder Blood." she huffs, slightly disappointing in the lost opportunity.

Reima "Other than having the possibility to kill yourself, you might also alert the Wild Hunt. So I'll say again, don't do it."

Flashback End :

After that lesson she realised the full power that she held at her fingertips, she was sure once everything was over and done with her and Reima would attempt to unravel the mystery of their powers. In all honesty she was looking forward to it, well, they'd do that after she'd fully become a Witcher... Hopefully after roping Geralt into completing her training.
